Ok so all I have to do is swap my spindles?
Can I still use everything else like calipers and mounting hardware

You'll need 92+ spindles and im sure rotors. Calipers should still work but I may be wrong, it's a rare occurance but it does happen.

Nope, the calipers are different. The early standard cab rotors were thinner and didnt cool as well. Thats why they went to the thicker rotor in the extra-cab and SS 454. If you are changing to 6-lug anyway, go with the 3/4T calipers too-they have a slightly larger diameter piston, and were made for that rotor.
