I installed the cylinders without too much trouble. I used a pick to get the clip off and a large screw driver to put it back on. The piece of wood worked great to hold the cylinder in place. Thanks for the suggestions.
Unfortunately, I still can't hold more than three pounds boost with the vacuum brakes while brake torqueing. I have two long Performance Friction shoes and I have the brakes adjusted so they just drag. Would a vacuum reservoir in the line from the tb to the booster help? I sure hate to go back to the powermaster, but that is my next step if I can't hold at least five pounds boost at the line. Any suggestions to help hold more boost?
