    Does any know of a rotor with a drum built in for the e-brake that will work on a 14 bolt?

    There is a company out there, I was doing a random search last night on a different but similar subject and stumbled across that. Do a net search and see what comes up.

    They come that way from the factory in some newer Chevy trucks. The drum is the inside part of the rotor.

    Not everyone can do that :( And some (but not mine) states don't allow that for inspection.

    My uncle has got a 14FF laying around out of a 2004 chevy 2500HD. It has dual piston calipers, and Internal parking brake, and I tell you... it is one nice axle. Id hate to see what he wants for it, prolly around 800-1000.

    As far a conversions, I say find one of these axles, butother than that, I dont know.

    I hear that 76-78 Elderado rear calipers have a e-brake in them, but I'm not exactly sure how they work out. It's on my list of things to do......:D

    I think there is a difference in the backing plate surface that will not allow it to be bolted to a drum type housing even if you did a complete changeout. It has been discussed on here previously. The only way I can think of doing it is to swap a 14FF with factory discs on from a totalled truck.

    They're called Drum-In-Hat rotors. They should be on most, if not all, GMC trucks that came with rear disk brakes from the factory starting in the early '90's. They will not simply bolt up as the rotor is MUCH different than the rotor used on 14 bolt swaps.

    Got them on my 72 Blazer, work fine. I went for rear disc, cause the mud would eat the rear shoes in a couple of weeks. With the park brake being drum on a rear disc setup, you would be in fore a lot more maintainance work to keep te park brake alive.

    Interesting.... how do they handle OE applications with this setup? Or a trans-mounted brake?

    For the original question... I've seen of a couple of successful swaps where the whole brake setup is stripped from a donor axle - and then the backing plate flange on the recepient axle is moved to suit.

    EDIT: Ford E350/450 are another good donor with the correct bolt pattern.

    I would have to see the specific state's requirements to know for sure, but I can't imagine that not being legal. My '71 Toyota FJ-40 has the same basic setup (except drum instead of disc) that is all factory.
