I plan on doing a moderate-serious build and a rear end with 32 spline axles and 3.55 ratio with a LSD would do wonders. I can’t afford and don’t have the knowledge to rebuild my rear end, what would I need to do to fab a refreshed rear end out of an 05+ into a 2002?

That won't work unless you cut and weld a bunch of brackets on the axle housing and the car's frame.
The shocks are moved outward on '03-up models.

You'd probably be best-off having some custom shafts made.

Also, it's 31 spline axles, not 32 (this will make a huge difference when ordering axles).

Lastly, '06 was the first year for the 31-spline axles.

Not worth it.

You would need to weld new shock mounts onto the axle.
You'll also need to use 03+ rims in the rear, and 02- up front. 02- will work in the rear, but will poke out past the fenders.


There are 02- 31 spline axles (which are shorter than the 03+ 31 spline), they were in Towncars ordered with the Limo Prep package...so pretty rare, and probably worn our by the time you find them.
Better off getting custom made axles for your 02- housing.

The rest of the panthers switched in the middle of the 05 model year (December 04 build date).


But really, 28 spline is plenty strong, unless you're doing a serious power build, you shouldn't need to swap.
