I got everything in finally, ended up using the gbody brake booster and master. Using the 3rd gen pedals i put some washers in to move it out a little bit to make sure id be getting full brake relase. The clutch master cylinder lined up pretty well in the factory hole below the brake booster. I did have to trim some off the pedal bracket, and I only used the two top bolts to hold the pedals in, but it hasnt been a problem at all. I did also do the adjustable master cylinder trick, without that I was nowhere near getting full clutch pedal throw.
