My 63 has had a front disc conversion done by the previous owner. I am unsure of what brand the parts are, but everything is new looking including the master cylinder and proportioning valve. Can i just add a brake booster to it, or is there more to it? Will i need any additional parts or have to make any other modifications? I was doing a search and ran across the Modern Performance Classics 7" 3 stud booster but the year lists 64 and up. Will this fit my 63 or is it different?
