View Full Version : A/C Compressor Question
04-19-2001, 08:58 PM
Does anyone know which A/C compressor the 81-91 big block crew cabs used? The R4 or A6? Or could they have used both? I'm considering buying a 76 parts truck with the A6 compressor and was wondering if it would be compatable with the 81-91 crew cab that I will purchase when I find a good rust free cab to buy in the future.-Thanks Mark

If you Email me with all info on truck I will look it up . But if the truck has been sitting a while the seal will be leaking around the shaft behind the clutch most likely .

Im 98% sure the 81 and newer use the R4-across the board on GM's.
