I have never seen MSD before the '75 period. I also have abunch of Midwest, Gratiot, Bell catalogs(these were similar to ummit or Jegs) from 1974 and I just looked into their catalogs and no MSD.
Even in the car mags you will not see any refernec to msd in the early '70's but you do starting around 75-76. The only ones are mallory, Accell, Echlin, Du-coil, Judson and several others.
Also I was refering to the earlier '70's when this car would have been worked on at motion.
