I looked at the Bouchillion kit - looked nice, but expensive. I made a plate that attached to the mechanical fuel pump holes ( I also kept the blocking plate to seal the hole) and welded a set of the universal brackets onto the plate. The main benefit (aside from cost) was that I could put a full size compressor in, not the "Shorty" that Bouchillion sells. I attached a second bracket from the other side of the compressor ears to the motor mount to triangulate everything for a solid mount. With the longer compressor, I had to move the alternator forward and actually run the alternator off the second compressor pulley. If you can fabricate the compressor mount, changing the alternator isn't hard.

Good Luck
