As they are both GM, if the control cables fit, and you have physical space, you should be OK. I'm not an auto electrician, but the operative phrase here is "SHOULD be OK"...
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Ok thanks I check autozone and they had a alternator for one year 866 for example and the cut off date was 88. But that was for a stock alternator. I might go out there and throw it in and see what happens lol.

I went to the shop one told me to use the the 2 side bolts and not use the third. Another told me to rebuild it. I thinking of getting a custom bracket for the third what you think

So here's the update I got to the shop that made the alt he turned it for me all bolts lined up but the third. Is it safe to not use the third or get a bracket made for it. Suggestions
