Killed Two Distributors and Don't Know Why!

Please note edited post above

Hey '67,

Is there anything possible outside of the wiring harness in the fire wall, the coil, ballast, ECU or Distributor that could be the problem? I plan on running some diagnostic work on it before I try starting it again. I don't think I can do everything you recommended, but I will try to do my best. I was just wondering if there is anything outside of the normal four parts that could cause a distributor to fail...
