I am currently upgrading my 64 C-10 to front disk brakes. Will a 1991 Booster w/ master cylinder and proportionate valve work? It came off of a 1991 full size Chevy truck. I have looked at a '72 booster and I can't tell the difference between the '72 and the '90 except the '90 has antilock valve that I would take off. Thanks for the help. Snowdevil
