Just talked to the guy that are going to be reinstalling my AC, I had removed it awhile back and thought I kept all the parts together and gave all them to him. He is telling me that it is missing a trangle shaped piece that is about 2"x2"x2" with a hole at each corner. I still need to go home and look around my garge and hope I find it there, but was wondering if anyone knew what he might be talking about. Maybe a picture that would help me look, or even a place I can buy a replacment part. He said it hold the compressor to the engine I guess. I seem to remember this, but can not belive I did not put it in the bag with the rest of the little parts for the AC etc...
