I posted my build in the 67-72 truck forum. I am using a '91 model clutch master, and the internal slave thats on the '97 nv4500. I just drilled a hole directly off the clutch pedal and gave the master cylinder a home just to the drivers side of the hydroboost. I had it all working fine, until the used slave cylinder decided to start leaking, now I have to pull the tranny and mucho heavy np205 back out just to change it. I guess that will teach me to try and be cheap and reuse unknown condition parts..lol
