Most of the later 80's Ford Thunderbirds came with 8.8 rear ends with disc brakes. My dad's does I know, but I was wondering if these would work ok on an XJ? I know that the springs are under the axle so I'd have to cut those off and weld perches on the top, but would the width be ok? I know of a few T-Birds that I could get one from, so I'm just curious. THanks

I used a 8.8 from a 89 lincoln mark VII, works great, is the right width, disc brakes, right bolt pattern too.
