Check out the tech section on gnttype.com. you will need either the pedal off a g body with vacuum brakes or, drill a hole in your existing pedal for the correct push rod mounting position. I posted a link on here once showing how to do that.

If you have a good junkyard to loot through, you can find a pedal and then visit your local parts store and get the rest.  There is a junk yard donor thread on the big board.  List is something like 34 pages.

I thought that the pedal bracket could stay put?  Just the pedal itself had to get switched, and the booster of course.

It's the one of the 4 that held my old booster on mine was converted when I bought it I recently swapped diaphragms

I'd redrilled my pedal based on some instructions I'd seen somewhere and It never felt really right. I musta had the hole just slight off.   felt like a tiny bit of binding at the start and then it would feel proper once you were partially into pushing it down.  drove me nuts I ended up just getting a vacuum pedal.  So something to consider if you want to reuse your old pedal.

I've done two of these powermaster to vacuum brake conversions.  Pedal bracket can stay.  You can drill a new hole on the existing pedal or you can get a pedal from a vacuum brake g body.  Don't need the vacuum block with the vacuum brake port if you have removed the EVAP canister, just connect vacuum line to the hard line that you capped after removing the EVAP canister. 


Rich has the rights on the hydro boost conversion
