Todd,



Sorry for the confusion. Though not likely appropriate for this tech. thread, in a nutshell, I was just hoping someone knew if beauty rings were ever an official FoMoCo/dealer-installed accessory?

I think the Ignitor II would be the best choice for keeping up the performance level - but I believe they are the same size as the original -anyone have a junker around? Holun and others have burned them up.

Still looking for my parts box with the tach drive dizzy unit for my heap - my wife seems to have "re-apportioned" the attic...........

I've got one of the Pertronix Ignitor (first type) kits for my '56 tach drive distributor - but its packed away (somewhere) with the original dizzy. I will try to find it and get the necessary dimensions off for comparison with the allowable space.

The original can only switch for a 1.5 OHM load or higher - otherwise the amps get too high for the switching transistor.

The way I see it, the module would be put in the position of the "last" set of points in the dual point grounding scheme. That would keep it "timed" to the rotor.......other ideas anyone? In your photo it would be the set at the bottom (for counterclockwise operation). 

I appreciate it Steve, pictures of a dizzy for comparison would be very helpful...I am thinking of going with the ignitor II when the time comes...

Todd - That price they gave you sounds a little too "opportunistic" to me - what model of car uses the points you found in the distributor? Are they from a Ford or GM product that can be identified? 

The ignitor modules simply attach to the point plate in the original screw holes for the points - so if you know (or can find out) the original application.....this shouldn't be impossible to figure out. The little plastic magnetic ring that fits over the 8 lobe cam can be adapted too.[quote]

The dizzy uses 2 sets of standard replacement points for a '56 T-bird.




I don't have another '56 or '57 distributor to compare to, and the picture of the Pertronix Ignitor plate for those applications isn't the greatest...

Pertronix tech guy wasn't real clear about how the plate mounts in the distributor. Does anyone have a picture of the Pertronix set-up in their '56 or '57 Bird?

So the "concours" 40s cars with beauty rings I saw had non-dealer aftermarket parts (a la the non-original Roadster spoke wheels installed on most restored Birds)? I'm surprised no one with personal knowledge has chimed in.

Not quite sure what your question is here Daniel...I have aftermarket beauty rings with standard poverty caps for a '56 Ford, just a matter of taste for me...the accessory wire hubcaps with integral beauty ring were installed over these same poverty caps.

I am far from a T-bird expert and can't make an informed comment about the correctness of the K-H style wire wheels, or the 40's cars you mentioned...

The Ignitor II kits sell for what.....$100 ? Kind of hard to justify $200 worth of "help" from Pertronix.....chances are its going to be a standard part.

The dual point distributors would make some serious sparks - and every racer and hot street car had one at one time - but........ they are a pain to set and the points still can bounce at high revs.

Well, I called Pertronix and they don't have an application for my W&H Du-point...but they will make one for $300+/- for me...I guess for now I will just focus on other things I need to do (like the rebuild of the 3 94's) and stick with what I have since it still works okay...

I do have one question though...all indications show standard points set-ups to have a point gap of .014-.016". I have no specs on what my point gaps should be on my Du-Point. Can anyone help, based on there experiences with similar applications?
