Ken - yes, those are disk brakes. This is a stock setup out of an '82 Camaro.
bznhafdzn - if you look close, you might be able to tell that the emergency brakes are hooked up. They're tied in to the stock brake system. The cables come off of the same connection point on the two sides of the rod that crosses the frame right behind the cab. I can use the stock adjuster.
Formula1 - the rear end cost me $175. The work was a lot more than that. The driveshaft was made by a local company. Yes, you have to get the tranny and rear end in place first, then you measure for the driveshaft. Like Phat says, you need to properly locate the driveshaft. We did it by taking measurements on another AD truck and comparing those to mine, then determining where center was. We did *not* relocate the shackles. Those are stock and in the stock position. We fabricated new mounts for the rear end, to locate it on the springs where we wanted it located.
phat - what can I say...different strokes for different folks. Not sure if you consider the '82 a late model. This rear end is about 1/4 inch wider than the stock AD rear, so it didn't require offsets or anything like that.
I'll take some specific shots this weekend to show how things are hooked up. The e-brakes, the springs to the rear, that sort of thing.
