You will need to get a master cylinder from a disc brake car for sure. The booster can be disc or drum, it doesnt matter. The various designs of master cyl are mostly due to afermarket replacements. If you use a drum booster, sometimes there is a difference in booster pushrods but dont let this scare you. The thing to look for is the depth of the piston in the back of the master. One design is about 3/4 inch down in the cyl and the other only about a 1/4 inch down in. As long as they match (the piston and the booster push rod) you will not have a problem.
