i've searched, can't find what i need. i'm running factory 72 a/c with a serpentine belt set up from a 95 chevy. i've got the 95 a/c compressor. i need to know which a/c condesor to run. i'm thinking about using the es12a refrigerant. what if i use 134? do i use the cross flow from a newer truck? from what i've read on the es12a, it seems i could use the 72 condensor. what do you think?
