Pertronic Ignitor in a Prestolite Dual Point?

Well I just called Pertronix Tech line and it sounds like I ordered the wrong unit. They said that my distributor takes the #1383 not the #1384 one that I ordered.
I am surprised there is that much difference from 69 to 70 SB dual points. Sorry, I steered you wrong. I guess Toolmanmike had it right, order by dist. number.
