Adjustable pressure regulator on HSR

If I bought an adjustable fuel pressure regulator for my stock tpi set up and then I bought the holley stealth ram without the adjustable fuel pressure regulator, would the tpi one fit on the stealth ram?
thanks

Doesn't look like it will. Why not just buy the HSR with the AFPR?

well i was gonna buy the AFPR for the setup I have now, and then switch to the stealth ram sometime soon.
so I was wondering if they were interchangeable.
thanks

no they are not. the HSR regulator is a buick grand national regulator. by the way, visit www.stealthram.com there is a board there that can answer all your HSR questions.
