My '76 C-25 had an engine transplant in a previous life. I was told the original 454 was replaced with a 350 from an '86 Suburban, which has been running strong for me for several years. But there was no A/C compressor when I bought the truck. So I am trying to figure out what type of compressor I should drop in and what additional brackets I will need. The attached picture shows what exists now. If it is correct that this engine was from an '86 burb, which compressor would they have used that year? Does anyone recognize this setup? Thanks!
