New Project 620

You destroy them when removing them. I forget what they're called, but you can find them at any hardware store, or at McMaster-Carr or https://www.clipsandfasteners.com

Push nut.

Stoffregen is correct on both counts. Don't try to save them as they are spring steel and will be damaged during removal. Most hardware stores should have a few different sizes. Use a socket that fits the perimeter and just push the new one on.

Some sweet pick ups from the Datslocos swap meet. Including (I think) an OEM original painted grill and badge. And a full center console with OEM hitachi radio and A/C controls

Decided to pull the the dash to do a dash cover repair. Hit a couple of hiccups. #1 dash insert was held in by 1 stripped screw. 🤦🏻 so had to pull the dash as one hole piece. Anyone know a way to remove this screw?

BTW my 620 came with A/C. Is it capable to run again? I know it used Freon

Well if you can find any R12 away you go. It's no longer manufactured or used since '94.  But R134a isn't compatible in R12 systems and it needs to be converted.

Any more info where I can read up on this?

Painted the headliner trim pieces and bolts to go with the black headliner that will be installed.

This seems to be a pretty good explanation of what is required.

R12 is a major ozone depleater (ozone O3 is in the stratosphere and absorbs the intense UV-B from the sun) which is why it became banned.

 

I'm assuming the AC was a dealer installed item and not from the factory. Aftermarket kits were a big thing in the 70's & 80's as many cars didn't have factory AC or at least hadn't been shipped from the factory with. I worked as an installer for a couple years (air, cruise, stereo) and we could put AC into nearly anything, available space was usually the limiting factor.

 

I saw some claims that you can still buy R12 (no longer manufactured but cleaned and reclaimed) however switching to R134a is a better choice.

Did you get that screw out yet?

 

Vice grips...

Been calling around to see if any shop can help me with the conversion. If no luck might have to do a delete. Wish me luck!

You really don't need to go through all those steps to convert to 134. Change the o-rings and install the R134 fitting and give it a shot. Yo should have a shop do the filling because it needs oil and the correct amount of refrigerant at the right pressure, but that is not expensive. Maybe a couple hundred bucks tops.

I have a shop up here that I use for all my A/C stuff. If you're willing to travel 100 miles, he does a lot of custom A/C work.

100 miles isn’t too bad. Where abouts?

Nice. Drop it off with Jonboy, stay at your parent's place. Done and done.

I'm not 100% sure but I think you need a special lubricant/oil or something for the orings .. 

I got a bottle of something with the universal kit I used to add ac to my 521... 

[Crashtd420]

This is something like what I got...

O ring lubricant...

 

 

... more click bait.

[iceman510]

It's essentially used as an installation aid to reduce friction and chances of damage to the o rings when installing.  The slightest nick can cause a leak.  Very essential in a production environment, maybe not so essential at home when doing just a few joints if you take your time.  

 

Typically it is the same as the lubricant used in the system for the compressor.
