See quote below. Basically there is a hole in the compressor bracket that attaches to the block. You turn that hole into a slot. This allows you to remove the compressor easily and more importantly without removing the entire bolt, which can be a royal pita to get back in.
^^^ this is the modThe mod is actually in the FSM. Rear bracket, the one that bolts on the compressor, and then is on the block with a stud. On 94/5, that has a hole for a stud. So, you put in the vise, and slice the hole open so you can slip it over the stud.
I don't believe so. I think GM took care of this in 96Does this mod apply to the 1996 ?
