The brackets are dependent on what they were installed in. If they were in a truck or SUV the alternator is on the drivers side and the a.c. compressor is on the lower passenger side. If you want to run a.c. at least for me there is not enough clearance. The brackets from the motorhomes, vans, and medium duty trucks move the alternator to the passenger side and the a.c. compressor on the upper driver side. The medium duty truck bracket that I have is designed for the ZF style pump. The motor home and van units typically have the Saginaw style pump. The big challenge on getting either bracket is GM has discontinued the part and most salvage yards do not inventory brackets so they are hard to find.
