Great. Thanks, guys.
So given that I'm going to replace the drum brakes with disc brakes, there will be no real mechanical difference between the '63 and '64 truck for me. The differences will all be cosmetic, like the grill, the headlight bezels, and the windshield.
Right? If so, I'll begin searching for a 1963-66 truck instead of 1964-66.
Thanks.
