I am wanting to do the 3/4 ton swap on a 68' but believe the brackets are different than a 71-72 truck.

Should I use one from a 68' version instead? It looks like a dual diaphram too but carries a different part # in the parts catalog.

If I use the 68' diaphram, what master cylinder would I use for disk brakes?

Anyone done the swap on an older blazer/truck?
