Is there a local A/C shop in your area? They will know which Compressor you need. Almost all Sanden Compressors that are made for aftermarket applications have the same 8 mounting ears on them and share the same dimensions. Since R-134a came out in 93'-94' it would be harder to find an R-12 compressor these days.
Did your kit come with the mounting bracket?
I think you need a Sanden SD5H14, which was the post-r134a version of the 5-cylinder SD508. Some people think the larger 7-cylinder Sanden compressors are a better choice because they move more refrigerant and seem more reliable - but I'm not sure if the mounting ears on both models are positioned the same (I'll bet Sanden has schematics online).
Be advised, you'll see lots of "Sanden STYLE" compressors available now (mostly made in China). I don't know how good those are, so some research is probably in order.
I have had no issues using the 2 cylinder York Compressors with R-134a. Just be sure to drain all of the oil out and use the Ester oil. There is a plug on both sides of the compressor body used to drain and refill the oil. When you fill it, lay the compressor on it's side and fill it with oil till you can stick a dipstic in and see 9/16" of oil on the stick. You can use a coat hanger, a 7" ty strap or anything that is straight and will fit through the hole. The Yorks are a good pump, but tend to vibrate and make a little noise. Thats why they had those huge Flywheels on the pulley, to smoothen out the vibrations. A Sanden is lighter and more efficient.
One of the problems in converting older R-12 systems to R-134 is the R-12 condensers are not as efficient as the ones designed for R-134a. So, on a really hot day the A/C wont cool and the high side head pressure becomes excessive which can cause seals to fail. If you have the CAA kit that shouldn't be a problem. If the York compressor you have was manufactured in the last 10 years it'll have the updated front seal.
On a side note, the Sanden I have in inventory, which is an official Sanden from CAA (I am a dealer) was made in Singapore and the Sanden Corporation is based in Japan.
It the CAA kit is their Daily driver kit, it probably has an upgraded condenser that will work with R-134a
If the kit includes one of their condensers it is compatible with R-134a. If it were my car that is what I'd use. There might come a time that R-12 and freeze 12 is no longer available.
Yes, their replacement condensers for the factory kits have more passages in them and are more efficient than the originals even though they look the same. Even the original Ford condensers which are called a serpentine design are very efficient. I have a 73' Ford Pick Up with a condenser out of a 70' Torino, a Sanden compressor and a real old Frigidair hang on unit using R-134a that will make the cab uncomfortably cold on a 98 degree day. Once in a while a chunk of ice blows out.
