CorAce Posted October 16, 2009 Report Share Posted October 16, 2009 I have an opportunity to get a good used windshield for my dime at a reasonable price. What I want to know is how hard is it to replace. Any tips, trick, products I should use. I would be saving about $200 by doing it myself. But if I break it I'm out a car until I can save up the money again (Months). Any of you guys in the PDX area willing to help for a bunch of cheap (PBR:D)beer? Quote Link to comment
VoidDragon Posted October 16, 2009 Report Share Posted October 16, 2009 My father has ran a body shop my whole life, and let me just say, whenever you can get a professional glass man to install your windsheild, do it. That being said, $200 seems a bit steep. I'd shop around. I know I'm in a totally diff section of the country, but I can't see it being that much of a price diff. The last glass we had installed was around 50 bucks. Let me just say that if you do it yourself, cutting one out is never fun. Unless the thing is so old the seal is competely gone. You will a long handled box knife. Not cheapy with the breakable blades. The Windshield goop and prep. alot of time in the dry. Good luck. Quote Link to comment
ggzilla Posted October 16, 2009 Report Share Posted October 16, 2009 Saving $200 seem a bit excessive. Can you save less money? :-) Tips from my glassman: * Don't get a new seal unless yours is unusable. Old ones work better, less chance of breaking the glass * Soften the rubber in hot water or in a box with a light bulb. Got it warm and soft * Use a bit of soapy water with the cord to ease the glass in * Be patient. Very patient. Take two hours if need be. The chances of breaking the glass are fairly high. I think we've all done it once if we've installed a few windshields... Quote Link to comment
CorAce Posted October 16, 2009 Author Report Share Posted October 16, 2009 $200 is what I would be saving over having it done. Ive done some searches online and the average glass shop (speedy glass and such) runs around $250-$500 with new seal, installed. not very budget oriented this close to Xmas. Quote Link to comment
71ka510 Posted October 17, 2009 Report Share Posted October 17, 2009 i did mine about two weeks ago.... just like a vw....... get some braided 1/4" nylon rope ( thats smooth ) i also used an old broken screwdriver that i rounded the tip off to help pry without tearing the seal........ like mentioned above... put the seal in hot water for about 25-30 mins.... then soak with soapy water ( keep some on hand to keep it wet) wrap seal around glass...wrap rope around seal in groove that body sits into..... overlap at bottom of glass ( about a foot or more on each side ). lay glass in position..... get inside car..... then slowly pull rope into car, SLOWLY to make sure you dont tear seal, break rope, and that seal is wrapping itself over metal lip...... when you get to corners.... get out of car..... and put light pressure on corner of glass as you pull rope inward with other hand ( not neccessary but helped me ) thats really about all there is to it..... and keep seal and rope lubed helps.... anyone car to add or subtract info feel free ( oh and took me about 45 mins by myself being pokey casue i didnt want to mess it up Quote Link to comment
datzenmike Posted October 17, 2009 Report Share Posted October 17, 2009 Talk to one of the guys at the glass shop, no! not the owner! Offer a case of beer to do it after hrs. Bet he shows up with everything needed plus the experience. Quote Link to comment
CorAce Posted October 17, 2009 Author Report Share Posted October 17, 2009 (edited) Wow thats perfect, I didn't even now where to start. do I need any glue or some thing like that, or is it just pressure fit? Zen, I like your idea as well. My fear is that if it brakes I'm F#@%ED.:blink: If I pay full price for a shop to do it they can brake as meany as they want.

ggzilla Posted October 17, 2009 Report Share Posted October 17, 2009 Don't worry. If it breaks just continue to install. Then you'll have one like us (cracked). Quote Link to comment
mklotz70 Posted October 17, 2009 Report Share Posted October 17, 2009 If they break it and don't have another on hand, you're still F'd. Bottom line...don't break it! Just go slow. Watch that the rubber doesn't get too tight around the cord and get torn. Don't push in on the glass so hard that it holds the rubber too much on the outside of the metal or it may tear the rubber as you pull the cord out trying to get the rubber to flip over the metal. Basically, you're trying to roll the lip of the rubber from the outside of the metal lip to the inside. When you set the glass into the frame, you put the metal lip in the rubber groove where it's supposed to be when installed. It will be sitting on the rope. As you pull the rope for the first foot where it's overlapped, it will just be pulling out since the rubber is already over. As youget to where the rubber is on the outside...that's where the fun begins....go slow. If you lose it....the rope gets pulled and the rubber is still outside.....start over. I was more worried about screwing up the rubber than breaking the glass. Make sure your glass has no nicks around the edge that would creat a weak point for a crack to start. If you find any...pay the shop :) Quote Link to comment
Guest 510kamikazifreak Posted October 17, 2009 Report Share Posted October 17, 2009 Is it the original windshield in your car? If it is chances are you will not be able to save the gasket..Pita to get out Going around the corners as you pull the wire or rope,do so in a circular motion alot less chance of damaging the rubber.. Dish soap helps in these areas (lube) Back fill the rubber to body with butyl. Quote Link to comment
CorAce Posted October 17, 2009 Author Report Share Posted October 17, 2009 ggzilla, I got the ratsun glass now... shooting for realm status:lol: 510freak, It is OEM, but I got more time than money so it can take as long as it needs to. So it sounds like I sould be more worried about the seal than the glass, where can I get a good quality seal? I would like to replace the rear as well, if this go'es well. What is bulyl?

ggzilla Posted October 17, 2009 Report Share Posted October 17, 2009 Black butyl rubber sealant comes in a caulking tube. It's not for the glass! But you can use it between the frame and the seal if there are any obvious flaws in the sheet metal. Some people use it on the glass but it rarely helps and makes a mess. Same with clear silicone rubber sealant. Oh and by "light pressure" on the glass they mean "feather lite". The glass is most likely to crack (in my experience) when you put a little pressure on it, like press with one hand... Quote Link to comment
coolioni Posted October 17, 2009 Report Share Posted October 17, 2009 In my state the insurance companies have to replace your windshied for free if you get it broken for any reason. I know of people that have thrown a rock at it and thern said it happened while driving. This way you will get it done for free. I have not done it, And I wont. I know it is insurance fruad, but people do do it. Quote Link to comment
71ka510 Posted October 17, 2009 Report Share Posted October 17, 2009 as for a good seal...... there is a gentleman on here that sells them..... also datsunlandsocal.com new-datsun-parts.com too intese restoration as well ( no back rubber ) and then there is ebay out of singapore so you can wait the 30 days to get it haha Quote Link to comment
Guest 510kamikazifreak Posted October 17, 2009 Report Share Posted October 17, 2009 I would source a "gasket" before trying to get it out. I recall that the oem ones have a urethane(or it at least seems like it is that stuck) strip around the outer edge of the windshield rubber,This is what makes it pita to get out.(going from memory been a few years since I have installed a 510 windshield) As to butyling it like ggzilla says,No need to do the glass to rubber ,But body to rubber,Pay special attn to the top(header panel),and a pillars when sealing. This is where leaks occur. Quote Link to comment
datzenmike Posted October 17, 2009 Report Share Posted October 17, 2009 Time of year is wrong for outside install. Find a heated garage and turn it up. Warmer is softer rubber. Use a Windex bottle with water and dish soap in it to keep everything wet. Quote Link to comment
MikeRL411 Posted October 17, 2009 Report Share Posted October 17, 2009 It may be a Southern California anomaly but in the San Pedro LA area almost all the pick your own part yards have a bunch of windshield installers parked at the entrance. Most will even go in and find the glass for you, for a good tip of course. Quote Link to comment
Figbuck Posted October 17, 2009 Report Share Posted October 17, 2009 Try it but, you could probably get a new one installed for less than $250. It's a lot of money if you don't have it. Go talk to the the guys at Apple Auto Glass on SE MLK. They do great work and might talk you through it. Then when you break it, you know who to talk to. Good luck and don't force it. Glass gets more brittle with age and windshields crack just at the last few inches just when you think you are going to get it in. Quote Link to comment
deadmonkey Posted November 24, 2009 Report Share Posted November 24, 2009 (edited) I am still kinda confused after reading this post a couple times. I've been looking on youtube etc on how to replace windshields... I'm guessing the modern way is NOT how the Datsuns are setup? Cuz it looks as simple as "put the adhesive in", "put the glass in", "tape", "let dry" and put molding back on. Does somebody have a picture perhaps? I can get a replacement seal pretty cheap here: http://www.technologylk.com/crl-windshield-gasket-1973-1978-datsun-truck-fcw271-lk-WBL271.html And I can buy a brand new windshield from a glass place for around $125. Like somebody else asked... is there any adhesive involved or is it just a pressure fit? If somebody has documented with pictures I would really like to take a gander. It's probably really simple and I'm just making a mountain out of a molehill here. === EDIT: I stumbled on a site looking for some Butyl... is this what you were talking about: http://www.ehow.com/way_5443659_instructions-auto-windshield-replacement.html BTW, I found a good site for weather strip and even replacement rear windows http://www.technologylk.com/__650/automotive-products.html Edited November 24, 2009 by deadmonkey Quote Link to comment
MikeRL411 Posted December 22, 2009 Report Share Posted December 22, 2009 Newer windshields are lain in place on a bed of adhesive. Our "real" windshields use a rubberlike seal inserted between the glass and the steel body. The seal floats in between, and if your are lucky it doesn't leak. Yes, there is a difference between what you have been reading and older autos. Quote Link to comment
hang_510 Posted December 22, 2009 Report Share Posted December 22, 2009 some issues w/aftermarket(china) windshields is that they are 1/16" - 1/8" thinner than OEM, and the seals, also aftermarket, are made to OEM thickness specs. they seem to deform (leak) along the pillars more than the top or bottom. the shops here WILL NOT replace YOUR glass when they break it, but if they supplied it (= $$$$) then they will. ive gotten pro quotes of $100 to install w/o the glass, so $250 inc glass is not excessive. +$75 for a seal.

sssr20det510 Posted December 22, 2009 Report Share Posted December 22, 2009 I put in front and rear glass myself wasnt too hard rear was harder than front, but it takes 2 people MS Glass quoted me 225 installed with seal Quote Link to comment
deadmonkey Posted December 23, 2009 Report Share Posted December 23, 2009 I JUST got my windshield replaced today for the 620. They did a great job and it is nice new tinted glass too, not like the old stuff. Installed with a new gasket, $180. I figure the headache and time it saved me is worth that much.
