Any info on a bracket for a Sanden 508....(508 is belt drive) Vintage Air and a few other calls turned up nothing except... never seen one, you'll have to make it. Already getting warm here in SoCal.
I'm sure others, like me, are interested in your results. If it works on a 350, it will work on a 455 with minimal changes. I used the factory '75 Skylark V6 compressor on the 455 I swapped into it so I know it will be close.
I don't think that anyone is making the Sanden bracket for either the small or big block Buicks.I have seen a few on cars and it was a custom piece.Just about all the people that I talked to said that they used the stock Buick bracket modified with a universal Sanden bracket that is available on the market.Lots of good measuring,mocking up and welding seems to be involved but the ones that I've seen look very good and almost stock appearing.
If you have the factory brackets you might want to consider a Pro6Ten compressor. It's basically a 508 Sanden with A-6 mounting points. It's a bit spendy but a better alternative to making up brackets.
