I looked into this, as I wanted to ditch the dead York compressor on my 81. What I found out was that the the clutch assemblies between the 82-86 compressors and the serpentine ones were way different as well as how the body mounted. Ultimately it was looking like the only practical way was going to be to convert to serpentine which was more of a project than I wanted. There certainly may be solutions I don’t know of, so if you come across any please share!
