A/C Compressor, which one???

[dailycutlass]

Hi guys,
Question? :?:
I need an new a/c compressor, but when I'm shopping online for a new one, there's a lot of different types.
Switch, non-switch, with or without clutch, etc...

Can anybody see from the pictures which compressor I need?
It's for a 1978 Cutlass Calais, 305 CID.

thanks!

It looks like an R4 radial compressor. You'll want to purchase it with the clutch assembly, I'm sure. I'm not sure about the switch and non-switch factor.

Yours has the switch. last photo, it's in the back of the compressor. also I recommend getting it with the clutch.

I got an ac compressor that I need to get rid of. Looks just like that except for the switch in back. It's in good shape, came off a 1986 grand prix with a 305 vbelt setup. $40 bucks + shipping and it's yours, comes with all the brackets too. I'll have a pic up for you soon, pm me if your interested.
