My coupe was r12 and the urs6 I had was r134a refrigerant if you want to keep the serpentine belt the pump in in a different spot lines are different , I think the way I have seen it done was ether one off lines to fit your application , keeping the v belt set up in my opinion ( bad idea ) then I'm sure you need to retrofit to change the system to r134a h block or the orfice in to the evaporator I can't remember witch car has witch
