Had a slant six, now V8, Can I swap Power steering brackets?

Brackets are specific to pumps. The early or at least 2nd gen A`s I believe came with TRW-Thompson, what I have. then there is Federals, look simular but are different with diff. brackets. then Saganaw with different brackets. The V8s got a larger cu-in. pump verses /6. I ran across a website that sold new repro brackets but I cant remember who. If I saved it I`ll post who. Hope this helps8)
