My '69 Road Runner always had trouble starting in damp weather (you could spit next to that car and it didn't want to start!) I installed a Delta Mark 10 CD unit and I never had another problem. Also, the points lasted 3 times as long. It was the same unit as the Heathkit. They were offered with and without a red button on the side to disable it while tuning so the dwell meter could pick up the signal. I collected a few of them over the years but never hooked one up again.
Great idea at the time.
When I bought my last '62, it came with one and the original owner saved all the literature for it including some correspondence he had with the company regarding how to make the factory tach work with it.
