Can you just change the pedal out to change from drum to power disc? or do you have to change the whole bracket under the dash?? I had drum brakes on my car and over the winter swapped a set of disc brake spindles and brake setup on the front, but i still am running my maunual drum brake MC, and pedal. I have the bracket and pedal for under the dash and the MC and booster for power disc, just havent got them on yet. Car still brakes very well with the manual drum MC. I have a 8.8 rearend with disc brakes in the back too. Everything seems to work very well but i would like to get the power disc set up finished. Probably this winters project. Thanks
