Thanks, Tom. I'm thinking a 1/2 ton manual cylinder may actually work just fine--looks like both the caliper bore size and rotor thickness are the same for 1/2 and 3/4 ton trucks. Is it possible that you used a 1/2 ton cylinder on your rig?

Man, I'm with you on the value of a good traditional parts store. Chain stores are practically worthless for stuff like this, which is why these forums are so great. Since my go-to parts guy retired several years back this sort of project has gotten a lot more difficult. I've always happy to pay a premium for good service. Real shame you often don't have the choice anymore.
