1969 Swinger 340 distributor questions

AdamR said
If Im not mistaken only 4 speed car recieved the dual point dist.

The dual points were available on automatics. I`ve had 2 and have 1 automatic car that has the Prestolite factory dual point as factory equipment. I thought the dual point was part of the early 340 package?

Well, me not knowing what an electronic voltage regulator looks like, I have to provide a description and hope you can answer that question yourself.

There was a blue, square unit with a single red wire coming out of the back of it, with a stud/nut on the front. The printed number on this box is P-3690732. (It was in a box like the rest of the car when I bought it.) This blue box is about half the size of a pack of cigarettes.
Is that an electronic voltage regulator?

The alternator number is 4111973. I have no idea what it is for, but it's a remanufactured generic parts store unit.

Thanks for the help!!!

George

Part 3690732 is the proper MP electric voltage regulator for `69 and earlier.

Did Prestolite make any single points distributors? I've got a 273 dual point prestolite. Never thought about it but it might be possible to run with just one set of points in it. Just sort of thinking out loud.

You can run just one set of points. There may be a wire that ties the two sets of points together that may need to be replaced or insulated. Just adjust the dwell to specs for one set.

I`d like to get my Prestolite dual point rebuilt , does anyone know of a service that can do it? The vacuum advance needs attention too.
