I think the best way is to use a Mopar (Strange is double the $$) master with a conversion plate to get the resivior angle correct. Make sure that the pedal ratio is 6:1 with a 1in bore master (dodge truck) and it should put you through the windshield.
Heres a link to a real trick master conversion plate i found on RJ...

I tried to use all GM stuff to convert from power to manual that I had from a 78 Malibu parts on my wagon and it was a complete fail...pedal feel was garbage and it was hanging the brakes up...complete disaster. And I had a "stock car turned drag car guy" friend give me a little tip on brakes...it doesnt hurt to have a little heat in them before u stage....he told me he rides the brakes in the lanes to build some heat so the car will hold better on the 2 step...I tried it and it works great.
