Ok Im def gonna go about it with the C2500LD brake rotors i have a couple questions:

1: when looking at aftermarket spindles am i looking for ones for 1 inch or 1 1/4 rotors? I have seen both on the site i would be ordering from, Just want to make sure i would have the right ones for using the factory 6 lug rotors from the 88+ 6 lug 2500s

2: Will the control arms from a C30 from the 73-87 model trucks work? I have a line on a pair from the same 1 ton im getting the 6.2 Diesel from for my project.
