I'm saving a '50, 3604 also and should be finishing up the mechanical side of it in a month or so.
Been derusting parts for machine tools, antiques and old cars for most of my 65years Big guy. Get you a good bench grinder and stand and put a course wire wheel on one side and a fine wheel on the other and start de-rusting anything you can hold up to the grinder. I do this with nuts 'n bolts, backing plates, grill baffle, grill parts, mirrors, glove box doors, horn, air cleaner, clutch and brake pedels, just finished up all of the parking brake parts from the foot pad back to the rear backing plates today.
It beats, chemicals or sand blasting unless you are dealing with a very, very bad case of rust.
I'll try to post a before and after picture of the brake parts.
