Kowalski I swapped my 99 and couldn't be happier. I used 03 spindles since the discs are larger. I had to have new hubs anyway, so I had a pair plugged and redrilled. I kept the 9 1/4" rear, but had 8 3/4 ends swapped on. Dutchman made me a set of axles that fit perfectly, then I put in a tru-trac. Bonus: it eliminated the c-clips. The truck drives awesome and I couldn't be happier. Now I get a huge choice of rims because of the Mustang interchange.
