Help me identify this ac compressor and approx value
 

I'm selling some parts that have been sitting in my garage and found this compressor I bought when I did the 3.6 conversion. I never installed it. Does anyone know what year its from and approx value? The momo 1/2" extension next to is is for sale too.

It looks like the one that came on my 3.6 ,which was from a 91 964.It might also be used on the 993. I have seen them on ebay for $75 to $500.Often available around $200 I think more if someone really needs it.

Should fit any Porsche that used a Nippondenso compressor, obviously 134a so it came from a newer car. Rebuilts on ebay around $150. Yours has been out of the car and dry for awhile, no telling what the seals are like, would need a rebuild. The rebuild kit is under $20 and easy. There is a pelican diy on rebuilding.
