Im tryung to learn people, please help. I just did a power disc swap from a 73 nova into my 68 nova manual. When connecting the rod from the power booster I noticed my pedal hung about 2"s to low (will not engage the brake light swithch either). I was reading threads on here but it confussed me. Here is my question could I go to autozone or pepboys and order a 68 brake booster for manuel transmissions and would it fit, what can I do? I know I cant use the booster from drums/drums to disc/drums.
