changing to disc brakes in my 71 torino, can I just ad a power booster or do I need to change the pedal. Also where do I get the porptioning valve. Can I get one at the parts store?

Yes you will need a new pedal as well as a disk brake specific master cylinder. As for the proportioning valve I'd buy an adjustable one so you can set it exactly to your liking.If cash is tight try to find the same car at the wreckers and get all of the above.
