ok this morning I put a plug in the vacuum for the power booster and it seemed to run fine but I couldn't drive it without brakes so I put the vacuum back on the power booster with a knew filter which it didn't have before and a check valve(how do you check that?)and drove it to the gas station holding the idle up with the pedal,put gas then stuck my foot in it broke the tires loose then it sound like it lost power then it would'nt idle
will a power booster from a 68 firebird work? it looks the same,thanks to everyone for your help
