I don't recognize these brackets. Any guesses on the application?
Thanks!

I would say mid 1970s 454.

Looks a lot like BB PS Brackets on 73-91 Squarebody trucks too?:hmmm:

Definitely long water pump era and the square hole, I think, to tighten the belt, without crushing the reservoir, was an early/mid 70's intro too.

Thanks guys.
Then it would be a 74 454 truck pump.
I didn't realize truck kept using the rounded pump vs the squared off pump used on pass cars.
Is it a hard to find part?
