Overall nice kit. The factory lugnut studs on my axles were too short to use with the thicker disc brakes, so had to buy longer studs. You will also have to make new brake lines for the axle and buy brackets for the end of the hose. The caliper brackets and everything else fit well and are good quality. The discs are 1" thick. I did have to do some very minor clearancing on the calipers for aftermarket wheels, but I believe stock rallys would fit no issue.

I have front disc and wanted to swap out rear to disc as well. Price is really good for a e-brake caliper kit. Got it installed today, no help from the instructions they are terrible. Running 67' axles and carrier so I had to use the little spacers included. However, instructions say it comes with the brake hose mount braket to weld to the axle. The kit does not come with these. So now I will be waiting on those until I can get the brake lines hooked up, bled and e-brake adjusted. Although while instructions tell you to adjust e brake it does not tell you how....I am assuming it is a mechanical adjustment of the threaded rod under the truck just like the drum ebrake is adjusted. If review allows edits, I will update next week when that is done and I am able to test drive.
