Does anyone know if 07 Rims (6 lug) will fit on a 93 (6 lug). Don't know if they change the last few years....

Yes, they should fit just fine. I have installed a couple sets of 6 lugs from 99-06 trucks on 88-98 body style trucks. They fit well and look great. The 07 rims should work just the same as the 99-06 rims did on the 88-98 style trucks. Good luck man!
