Hello, I need a power steering pump/pulley/bracketry for a 1970 Buick GS 455....What do you have? Thanks, Wayne
If Matt doesn't have one I know I do - Almost positive 350 is the same & I just pulled the setup off a Skylark.
If all else fails . . . . . . I have the Big Block Brackets as well. The 2 Outer Steel ones as well as the Aluminum one. I also have the correct bolts if needed . . . . Brett is correct, they are specific to the 455 (otherwise you'll have belt clearance issues) .
The Aluminum one will work on either engine. The Steel "Outer" Brackets are engine specific. (So you're right on the aluminum one) .
