No I'm SURE you'd have to fab up a new bracket. They SHOULD come with the lever, but as new as these setups are, the pieces should be still available from the dealer, and fairly cheap. Used would be a better option. I paid $40 for my complete camaro calipers with e-brake from the wrecking yard.
The problems with the Camaro stuff are rotor thickness, rotor bolt pattern/axle flange size, e-brake, and mounting bracket.
Personally I think with all the effort going into the ElDo stuff, the Camaro ones could be made to work easily (at least bracket-wise). The e-brake problem is simply the same as the ElDo in regards to the way it is routed and connected...both the routing and caliper connection is different than truck drum setups, so there would have to be some adaptation there.
The rotor difference is a little more difficult. The axle flange could be turned down fairly easily (or rotors opened up) but the bolt pattern would be a major issue (limits donors to those with same 6 lug pattern) and along with the bolt pattern, is finding a 6 lug rotor close to the right diameter, with the right width. FYI, just noticed some Astro vans with 6 lug wheels, wonder what the rotor specs are on those?
I still think that if someone sat down with the right material and tools, the bracket would be easily fabbed up. The rotors, someone just needs to sit down and look at "all" likely donors, until something is found. There has to be something out there...after all, I've seen .5" thick solid rotors with a GM 6 lug bolt pattern.
The only other choice I'd attempt is just going with a newer disk brake truck rear. Save ALL this time and hassle. Or at least most of it, as the e-brake would still be different, and spring perches probably need moved. At least there is no guesswork in that.
