use rev chain case bolts 1/16 thick bolt head ,the 2 screws in the foot well need to be turned around,screw head on inside,2 rivites in tunnel top up front before drivers,i cut track,looks like challenger cut v on tip of lug,ez
replace bolts one at a time,check driver to window alignment to be safe.
when i did mine big john sold me the track,axle with drivers off a 04 rev went right in,tunnels are same width.cut a notch in rear brackets for side of track or put rev brackets on there flat.
it rubbed a little at first then it clearenced itself.
