Its basically a direct bolt on...
You have to drill one hole in the caliper bracket.
An 8 3/4 has a 5 bolt flange and the jeep caliper bracket has a 4-bolt flange. You have to drill a hole for the very bottom flange bolt. The other 4 are a perfect match.
I went to a junk yard, found a jeep with rear disc, removed everything, spent 25$ at the junk yard. Went home drilled the hole in the caliper bracket, mocked everything up, put on a wheel and tire and everything cleared.
I should mention I have not figured out the emergency brake. I don't think it will be that hard. Just need to get a cable made that is long enough and has the right ends for the jeep ebrake. I may not even mess with ebrakes too.
