I am not sure what all crosses over between Troopers and VXs...I thought the front suspension was basically the same, other than maybe the spring rate on the torsion bars, but I don't know for sure.

Anyway, regarding Troopers in 95 they went to the wider track which should be the same as the VX, so the 96 would be fine as a donor in general. Having said that, the diff brackets and crossmember should be the same for all 2nd gen Troopers.
