The new receiver dryer I have (and looks like all that are available) have an inni port instead of a outi fitting. See picture on right side.
Anyone know where to get a fitting to put in there?
Has anyone that has removed the condenser have any tips for getting the 2 lower bolts out that look like you have to turn them into the condenser slats? Not a lot of room down there.
On one of the fitting there was a copper cone washer. I think someone here brought that up a while ago. Where to get a new one?
For the fitting, these folks should have what you need.

Seco Seals makes concical copper seals in 37 degrees and also 45 degrees.
I'm pretty sure you can still get all those cone washers from Benz for cheap. I used the washers and also Nylog, that stuff works great on sealing joints. Perhaps you can get away with just using the Nylog and no washer.
On the side fitting can you not just remove that coupling and then screw in the pressure switch directly? Sorry been a while cannot remember which one is the temperature switch and which one is pressure.
Daniel, the fitting on the old one is not removable.
Any thoughts on throwing a new compressor in there vs trusting the unknown 40 year old one? Id hate to do all this work and then have to replace it later
I'd say it's a no brainer to replace the compressor now. It's a prick of a job on the 6.9 but for sure you'll kick yourself later on ;D
If you still have the cone washer you can re-anneal it if it's in otherwise good shape. Heat to incandescence with a torch and plunge it into water. Wham-O, good as new. I've done it many times, including on AC system. No problem at all. Cheers,
Need help identifying part numbers for the lines that connect to the compressor.
1. the one in front of oil pan that has foam on it.
2. the one that goes from compressor to the condensor.
First two Photos are of my car, and then one of one listed on ebay, but I cant tell if it is the correct one. These lines seems to snake around under the engine where you cant really see anything.
Still trying to wrestle condenser out of car. The 2 support bars I got removed, you loosen the bolt at the bottom (conveniently tucked behind where you cant access it.) You only need to loose and then you can pull the end off the bolt.
Still no room to get it out, looks like I will be pulling the radiator to accomplish.....
I found what may be the fitting, but need to check thread sizes as they are not listed as metric

Robert that last hose in your pic I don't think is the right one. From memory on mine the manifold hose connects on the driver side of the oil pan to the return hose which comes from the evaporator. There is a large coupling at this point with a bracket bolting it to the oil pan.
I ran into the same issue with mine not getting clear info on the hose part number so I just ended up reusing my manifold hose after I flushed it out with isopropyl alcohol.
I assumed that radiator was already out. I guess that's why I was puzzled that it was hard to remove condenser. Sorry, my bad.
