C15/C25 rotor question.
 

Hi there,

I have a 1976 GMC Sierra Classic 1500, which I've converted to 8 lug wheels. By doing so I lost my drop spindles and now I've decided that it needs to go low again. Are the rotors, wheel bearings and spindles (shafts) all the same on the 2500 models from 73-87? I have no clue where my front suspension came from as the seller had no idea either and he mentioned that there is a difference in the spindles, but all I can find is a difference in the spindles on the C10 models with the different rotor thickness, 1" v 1.25".

I need to make sure that I get the correct spindles as I'm in the Netherlands and I need to have them shipped from the States, and if I get the wrong set it's a waste of quite a bit of money.

I found the Western Chassis spindles but they don't mention anything about the rotors.

Thanks in advance.
