Anybody knows what parts needed when changing from R-12 to R-134a in a -88
780 with ECC and B280?
I have 2 part-numbers from Volvo: Basic-kit: 9145660 and a secondary(?) kit: 9134032.
I need to know what parts these kits consist of, as I can probably get some of the parts cheaper from a local AC-shop.
