Re: '66 nut

Well I was hoping that someone with a '66BB A/C car would join the discussion and maybe have pics or info on what bolts/nuts secured their stop/spacer and the thread count on their assembly. Anyone?

Re: '66 nut

Gary, I think we see this situation quite a bit. The drawing can only be done one way, however, an item could be installed several different ways. Bolts, Cotter pins, Hub Cap spinners, and we could go on and on. Some workers might have found it easier to install in the reverse order of was drawn. Maybe left handed vs. right handed workers.
