The a/c is not going to work in it's stock location. I will have to go to an alternate location probably using street and performance's sanden compressor and mounts to put it up high on the passenger side. The drive shaft will have to be modified no matter what. The truck was a 5-speed previously. I figured 4" off of it before moving it forward 1". Now I assume 3" shorter but I will check that out before taking it to the drive shaft shop.
