Rear end Swap

I found a Ford 8.8 rear end that I want to but on my '87 wrangler. My question is this. When getting a lift kit for the jeep do I need to get anything different? Are the springs the same? The u-bolts? etc.
Thanks in advance for any help.

You have to move the spring perches ont he 8.8 so that it is the same as the D35. Then you can use the same springs. As it sits though the 8.8's perches are a slightly different width than the D35.

The U bolts are also different because the axle tubes are much larger on the 8.8. Any driveline shop can get/make them for you.

I knew spring perches where different. I am getting the rear end kit from M.O.R.E. So if I weld the new spring perches and shock mounts on the only thing different for the lift kit would be the U-bolts?

The rear end has disc brakes so how do I deal with that? Do I need a new master cylinder?

The only thing that is an issue is the e-brake...you either have to fab a bracket for it or I think that there is an aftermarket kit for it.

I'm in the process of the 8.8 swap right now myself. Here are a few resources I am using for my research. Hope it helps.

I used the 8.8 e-brake lines. You can cut them to the 35 lengths and use cable stops to make them work. Google Ford 8.8 ebrake in yj and its one of the first links. It's a jeepforum link. Need hose barbs and that's it.

You don't need to do anything new to the hard brake lines. Use the 35's T for the brake lines on the 8.8. Unscrew the vent tube bolt thing from the 35 and it'll screw into the 8.8 vent tube hole along with the brake line T from the 35. I got the kit from nowhere2jeep. Worked great
