Replace old AC compressor with late model compressor
My Harrison A6 compressor went out. From what I can tell used ones are very hard to find, and no telling what shape a 40 year old compressor might be in, and anything new or rem'd is crazy high.
I was thinking, if I'm going to do the work and spend the money, why not use the compressor and brackets from a late model Chevy? At least late model parts would be easier to get when needed, and I'm not interested in keeping it original. I just want cold air. I searched and found posts on converting from R12 to R134, replacing the compressor with a Harrison clone, etc. The truck was converted to R134 before I got it so I don't know what all was replaced. A flush and new dryer would be a must. Will late model mounts fit my 454? I would flush the system, replace the dryer, mount the late model compressor and recharge it to 80% of factory R12 spec, but my gut says I may be missing a lot more. I don't see this being too difficult as long as I can use something with a v-belt from the 80's. I could also do serpentine and change everything if really necessary, or am I really opening a can of worms that I'm not going to like?

Re: Replace old AC compressor with late model compressor
I replaced several reman compressors in 5 years. They just don't last. I got this sanden style in 2022 and have been very happy with it.
