Moving alternator on a 350

[fatrat]

I am looking to move the alternator from the right side to the left side. The problem I have is how to identify the proper bracket to mount the alternator to.., I have a long water pump with the power steering on the lower part of the motor on the left side. The P/O told me the 350 came from a mid 70s Camaro. I want to stay with the V-belt I now have and I need some advice on what GM part number or bone yard engine application to help find one. I am replacing the wire harness with a new one and the wire harness has the alternator on the left side. I realize that is where the AC would normally go, however I see a lot of photos with the alternator on the left side..... I have a photo of the engine and any ideas would help. Thanks
