I am posting this one to provide a parts list to everyone. This parts list is something I put together to completely replace all of the parts in my 1990 AC system. The main reason for this was to do a conversion to R134a.
This should help individuals doing R134a conversions or for people who just are looking for certain parts. Again, this parts list is only verified for RENIX era. Some but not all 91+ parts may be interchangeable. If you find parts that work with later years, please feel free to add to this thread.
Main Parts
Evaporator Core
I purchased the following part, but it didnt look like the original. If i were to do it again, i would order from the second link since it matches the original. I didnt have any fitment issues, but it makes me warm and fuzzy to replace with the same type\style. If you replace this part be sure to replace the heater core because they live next to each other.

Compressor
To make it easy, i basically replaced the Original SD-508 Compressor with its R134a counterpart 4514 (5H14). Its 7 groove, but works fine with our 6 groove Serpentine. (FYI you can also find this part from the same seller on Ebay for a bit less)

Evaporator (Expansion Valve) to Filter/Drier
This part is not easily available. I had it made (Macs Radiator is local), but according to my local Jeep dealer it can be ordered from them. Jeep dealer told me part number 4773305 for around $75... but i dont know if this is the right part; again I had it made.

Fittings
These fittings are for the Compressor that I purchased above. They will also be needed for any compressor replacement that has different size fitting threads. If they are the same size (like the original SD-508) then you will need tube-o fittings that I have not listed here. They are available from JeepAir also.
