honestly ive been working my ass off lately
its not too complicated to swap the discs on the back
even the e brake setup is super simple...thats if the guy pulling the stuff gets every thing you need
THINGS YOULL NEED
both left and right backing plates and dust shields
if you want e brakes youll need to grab all the little parts from the e brake shoes, lever, adjuster etc
you can purchase every thing but the lever new from Vato Zone
grab the calipers and rotors too
i utilized the ZJ brake cables and the splitter plate they go into that bolts to the bottom of the body
i also utilized the stock hard brake line from the zj and the stock soft line for the zj
its good for at least 6 inches of lift
If i had it to do all over again i would have had machinist Paul open up the backing plates and drill the holes to bolt it to the axle on his bridgport but you can do it your self with a sanding drum
you'll also need two of these to properly space the bearing and seal

Things you should know:
pull the parts your self
i found out the hard way that you can bolt the backing plates on basically upside down or on the wrong sides rather, as the bolts are symmetrical
while it didnt hurt any thing i did cuss a lot when i had to tear it all back apart
