Dart IRS

Track width would be a problem. I have a complete rear end out of a Magnum sitting on the garage floor and its 59" between the backing plates. The whole rear suspension drops out as a unit mounted on a X-frame with all the control arms intact so figuring out that geometry wouldn't be a problem. The mounting width for the X-frame is 42". Four bolts and the whole thing comes out. The only thing you need to add to the car is the pads the the coil springs will contact and shock mounting position.
