Chris, I wish I had seen that sooner, I'm on my shift now and they last 48hrs. I won't be at home till Fri. Reading your last post I'll tell you what I did first. I used the MC/booster and pedal assembly from a 75-79 Granada and the proporitioning valve from a late 80's Chevy 1/2T all from the salvage yard. The booster is a small 9" and you'll have to trim the pedal brackets to fit under the dash they have a large amount of extra mass to them. It workd fine with no problems till I decided to dress things up and changed it all out.
