Check Cadillac suppliers too.

From my website HERE I use the plumbing fixture.

Ask them who the manufacturer is. Bwahahaha! When I restored the top I could not find that part so I had it zinc-plated. Like all the other parts on that convertible it was rusty and the plating process involves soaking in hydrochloric acid and maybe hydrogen embrittlement weakened the thing. Search hex head shoulder bolts. You will need all the dimensions if you call somebody.

Fastenal, Granger or Google o-rings lots of people out there selling.

housing installed with coil which means I didn't detect the leak this time. So far a different housing might be helping me. Time to finish charging and see how it works.

Probably oil on the seal there.

What you need is a shade tree mechanic.

Something that I am not understanding. The air conditioning compressor which is a 1955 general motors A5 leaks refrigerant. I pulled a vacuum and it holds overnight and you can't get any better than that. Add some refrigerant and I'm getting a leak at the front. That is after changing the seal and o-rings twice. It seems that pulling a vacuum would leak first since it's trying to pull in relatively small molecules like nitrogen and oxygen whereas the pressure with the refrigerant is large complex molecules which would leak less. It probably leaking when it's just sitting since when the compressor is in service the seal area is under a vacuum. I didn't have this much problem years ago when I couldn't find the right o-rings. I just cut and glued them with super glue and it all worked.

Perfect!

Might be where the word Boat was first associated with Buicks? Yeah, but that dynaflow translates to "does not float"

When I replaced the tattered boot on my working power brakes, the first time I applied the brakes they stayed applied until a few minutes after shutdown. Venting the boot and it worked as designed again. If that does not work for you call the supplier.

A short piece of brake line between the shaft and the end of the boot will vent it and get your brakes working as designed.

The corrugated bellows at the front of the booster needs to be vented if it's sealed too good the brakes hold lock until you shut the engine off and it bleeds down.

There is never an end to these projects. Anyhow you will notice that the front of the air conditioning compressor is missing some key parts. "Somebody" broke a wire off that energizes the clutch on the compressor. Easy enough to change out the coil but I figured I better check to see if the rest of the compressor is sealed. Not even close; the front seat was leaking again. It was working when I took it off the car. I even put a service valve on the compressor pulled a vacuum and added some liquid refrigerant and there was still some pressure in it when I tried to install it again. Just a little more disassembly and the seal was replaced with good results. It was in the '80s here today and it cooled so good that the wife was complaining about being too cold.
