Hi, and welcome to the PI BB.
I replaced the dual points in my Mallory dist with a Pertronix Ignitor in my '74. The dist body at this point only has the weights and springs in it to control the spark advance curve. I've had it in my Pantera for about 2 1/2 - 3 years now and it's operation has been flawless.
The Ignitor will do it's thing whether it's in a Mallory, or a stock Ford dist. Once you remove the internals, any dist just becomes a housing only controlling spark advance.
