Just put a Jaguar rear in a 55 TF and it was one of the easiest we've done. Just 4 hrs from start to waiting on a new driveshaft. Oops, still don't have the trailing arms hooked up but that shouldn't take but a couple more hours. Also has a Nova IFS and I'd bet it's going to ride and handle super. Of course it's days as a truck are over since you wouldn't want to haul anything that wouldn't fit in a Jags trunk. Much easier than a Kugel, Heidts, or T-Bird/Cougar/Lincoln IRS. They came in 53, 56, and 61 inch widths with the latter being just right for the 55.
