Are the 88-98 2wd 2500's five or six lug? Are there two different 2500's like the 4wd? I.e. 9.5sf or 14ff? Like a light duty and heavy duty 2wd 2500. What I am getting at, is that I think that a 2wd 1500 and a light duty 2500 use the same front spindle, but the 2500 would have six lugs, allowing me to run a 9.5sf in the rear of my C1500 daily driver with a 2500 six lug front rotor. Ideas? I doubt I could find a 9.5sf out of a 454ss. Plus I don't want to buy drums and zxles to convert to 5 lug.
