I plan on running A/C in my MK4. The engine is a 2001 4.6L 2V out of a Mustang GT. The FFR headers hit the back of the stock A/C compressor. As it bolts directly to the block, I'm not sure of a solution to this problem. Is there another compressor that will bolt into the stock location that is shorter? Is there a mount that locates the compressor down below the header. Any help would be greatly appreciated.
