1974 620 patina perfection

[hobospyder]

They are different widths and 520/521 tailgate hinges are welded on to the bed and you remove pin to release where 620 tailgate hinges have 3 bolts each that attach them to the bed

NICE, thank you sir!

[hobospyder]

I tried to see if i had any pictures of a 620 tailgate removed or even the hinges but alas, my photobucket fails me. Sorry.

 

And dont call me sir

[thisismatt]

dgi has graciously offered to help out on the tailgate, I've found a tailgate on Clist but he suggested that I make sure that it wasn't for a 520/521, anyone know what differences to look out for?

Here's a pic of it, unfortunately there aren't a lot of options on this coast.

 

That's a 620 gate

[hobospyder]

that picture was not there when i was posting. otherwise i would've said the same thing 

[TDCTDI]

And dont call me sir

Terribly sorry ma'am, I'll try to remember.

[hobospyder]

much better, thank you

[TDCTDI]

It's kinda fun watching water beading on a crusty truck.

More boring crap...

Removed seized adjuster by heating up the housing & then reassembled using lots of antiseize.

 

Then installed new shoes, wheel cylinder & hose.

I like it

 

PB plaster the upper bushings that need replacing then put a jack under and lift the drum up and you can replace those bushings ezer when trying to unscrew that bolt

[TDCTDI]

Thanks hainz, I'm doing one little bit at a time, I'll just have to order some more parts.

 

I did get that tailgate & someone double walled it at some point.

 

It doesn't look too out of place.

That gate looks perfect :cool:

mklotz70, a long time member here, offers a nylon bushing set that are much better than stock.

[TDCTDI]

Thanks for the info, I was interested at nylon but the ad says they're urethane (& energy suspension). I've tried the urethane route before & 6 months after installing them, the car had wicked on/off throttle pull due to deformed bushings. I vowed to never use them again, especially since the supplier said they'd replace them if I paid shipping both ways, that cost more than the bushings did. I never bought anything from them again.

[banzai510(hainz)]

the rubber ones don't last that long either  Im on my 3rd set

Good to know, any reason you haven't switched to the urethane kit?

[hobospyder]

Because hainz likes stock

[dgi]

 I agree.  I'm glad you picked that one up.  Certainly looks more appropriate on your truck that the one I have would have been.

 

I'm watching your progress, so keep posting as you work.

Thanks again for the offer.

More boring crap part deux

Maybe the PO was right, it didn't look like the brakes were ever adjusted & all I needed to do was adjust them. This adjuster was seized also & just a little heat expanded the housing enough for it to slide out easily.

 

I found that my battery post terminal cleaner does a wonderful job of cleaning the adjuster.

 

And the housing.

 

Here's all the wondrous, chunky, funky-ness one would expect from a brake system that has been untouched for 25+ years.

 

And here it is all back together.

[TDCTDI]

I drained the varnish out of the tank today...

At least until the shellac blocked the drain hole, I drained about 6 gallons out.

[banzai510(hainz)]

when I do my brakes I take the bearing out(whole hub) to pull the drum.

 

I cant believe you could get the drum off without still leaving the hub on there. Mine I have to separate o the ground with PB plaster and 2x4 . Wasn't EZ.

 

I would put anti seize behind the plate but Im sure you know this already

I gots mad skills with the BFH. "Mad" being the operative word.

[Stoffregen Motorsports]

Hopefully you didn't bend the drum with all those mad skills.

 

Is it running yet?

[TDCTDI]

It's been running since the carb rebuild, I still need to drop the tank & flush it & the lines, get the brakes working, since it's an automatic it's all go once in gear & replace the water pump & radiator. After it's drivable then I'll get the exhaust replaced, it's rotted off after the flange to the manifold.

[banzai510(hainz)]

be honest Im amazed how you go that drum off. with the hub still on the truck.

I have 3 sets of 521 drums and PB Blastered them and put the hub on 2x4 and then pounded with a 3 pound slege all along the back side to even get it to move.

Got drums turned and put Antiseize on mating surface reassembled
