Herm. The compressor is an old York?

If so it will be the same as an 81 or 82 280e us model.

I also have an engine for a us 280 that I bought from a salvage yard in Texas that has some other compressor on it that looks modern. The old york units are really not compatable to modern refrigerants, I understand.

I would try to use r12 if I wanted to keep the York style compressor.

If you like I will go out and see what that one is.

Also there is an adaptor available from (Vintage air?) that allows one to bolt up a modern Japanese compressor (not sanyo but a similar name).

Good luck,

I own a euro 280e 1984 model.
