Gotta add another positive result to the thread. Can't beat the price...and only a 'motor head' notices it's not stock...oh, and it works great.
With the old distributor, my idle varied by 100+rpm each time I returned the throttle, making it very hard to get idle and timing correct, so I dropped one of these in my `66 Belvedere II Poly 318...no more problems!
I must admit, I could have been the "1 millionth customer", as mine did not work right out of the box. BUT(!), to attest to their customer service...A quick phone call to these guys and we were trouble-shooting over the phone. Short of it...they sent me a new module, I dropped it in the distributor, and was off and running...smooth as silk. Haven't looked back since.
They tell you you can simply cut out your ballast resistor and the wiring. Well, there's a little more than that. You have to connect the wires that go to the resistor together...be it a splice or a jumper. What I did was to gut the resistor from the backside and solder in a piece of 14 gauge wire in it's place, making it the 'jumper'. Hooked everything back up so it all looks original. Now, if the next owner wants it OEM, all they have to do is replace the ballast resistor and drop in an old distributor.
Unless you're a fanatic about having points...or purely Mopar parts, this has to be the easiest (cheapest) way to add reliability to the ignition system.
