Started on rear disc setup

So I am also getting ready to swap over to rear disc I have an
8 3/4 and the brackets and calipers are off a TJ wrangler only had to drill one additional hole and it bolts up perfect have not tried the rotor yet hopefully that will fit not sure if any of you guys have tried using the TJ brackets and calipers yet I am not sure if it is going to work with the original master cylinder and proportioning valve or if I need to upgrade this stuff as well what are some of your guys thoughts

I'll keep watching as I want to do mine next summer.:popcorn:
