Even though I had an R4 compressor on the Blazer that was updated and used R134a, it did not support a 6 rib belt that my A/C relocation kit required. I ended up having to disconnect the lines and "re-collect" the coolant. I forget that the metal lines can be bent pretty easily with the right tool, so I'll give it a try and see if I can keep them. The Gen VI motor is also too smart for its own good and, as a result, will not regulate my A/C, so it's going to be directly connected to the switches. I could have made a GenIII engine work with the A/C (Something to maybe ponder if anyone is considering a swap or wants to prove I am wrong).
