Hi, Problem I got is that I pulled the spindles from my 72 chevelle it's got the bolt on steering arms, when I put rotors off the 70 chevelle on these spindles the rotors hits the big bolt that holds the backing plate, it's almost like the rotor is too close to the spindle. I found that the inner seal flange is larger on the 70 spindle, does the 72 spindle use a different rotor and or inner wheel bearings? I could take apert my 72 elky but if someone has info it would sure save me a lot of work! thanks TC Jim

I think I just figured it out! I believe the spindle on the 70 is actually off of like a camaro or something, the 72 spindle is about 7.25 inches tall and the spindle on the 70 is about 8 inches, and I had an original rotor from a 70 and it fits the 72 spindle just fine. Jim
