I have an R-4 pancake style air cond. compressor on my 82 ElCamino that needs to be replaced. I also have access to an R-4 compressor from an 88 Monte Carlo SS that I would like to use. Both are from a 305 engine. My questions are:

Will the hoses from my 82 system work and bolt up to the 88 compressor?
Anything else I need to know about?

Thanks for your help!

Yes.
