I just spent a good while looking at electronic ignition "stuff". ACCEL used to have a mag-trigger/Chrysler-style distributor, tan cap and all, but since Holley now owns that name, very little of the earlier stuff is still around, much less for Mopars. Unless you want one of their MSD items.
They do still have a version of the old Mallory UniLIte system in a conversion kit, though!
Seems that most of the point distributor electronic ignition conversion kits are repackaged Pertronix Ignitors, from looking at the pictures of them in RockAuto and such. The Pertronix catalog, which I finally downloaded for easier reading, has a graph of their Ignitor system and it's spark energy vs. a points system. Much more juice in the lower rpm ranges, but matches the points system from about 5000rpm+. Rather than the Chrysler "paddle wheel" reluctor, seems they have that stuff built into the bottom of a funky-looking distributor rotor?
I did find that A-1 Cardone has NEW point distributors for B/RB motors. Price in RockAuto was less than the reman point distributors from other companies. But those items are a "broad-fit" item, which have OEM part numbers they replace from 1960-1971, which also means a "generic" advance curve rather than an application-specific curve per swalloe.
This also means there has to be a supply of adjustable vac advance canisters around, somewhere, to feed the building of these distributors, too.
End result was that I didn't like what I found in Holley/ACCEL/Mallory or in Pertronix, either one. I might be inclined to use a A-1 Cardone item (even if it came repackaged in a NAPA box) and then set the total advance and hope the resulting initial advance was about 10 degrees BTDC or so. So much of what we used to have is now gone or combined with other product lines to "vanish". Standard Motor Parts has some ignition parts, too, just as their have lots of other car parts, too. So that might be an option, but possibly the same options as others might have.
A while back, I looked at the Mancini electronic ignition items. One of their kits seemed to mimic the Mopar Perf kit, which was good. The other one seemed to be more generic in nature. Pricing was good, too. At least they have a heritage in Mopar Performance items, so they ought to know what's what in that area, I hope!
I know there have been some comments about where various car parts are made these days. Unfortunately, not everything is made "here" any more, but "some where else". It's been said that certain origin-countries' items are inferior or have a higher failure rate than others done domestically. I can see that, BUT then I was in the Carter fuel pump catalog the other day. Seems the Carter manual pumps come from S Korea and the EFI modules come from China. And Carter is a very respected name in fuel system products. So my point is that all of these parts, where ever they come from, should all be built to a particular set of blueprints and criteria, no matter where they are built. Same as to failure rates and related quality control issues (a KEY point to consider!). They all have the same warranty coverage, no matter point of origin, too.
In the case of a suspected pre-mature failure, it's not that the one brand of part failed allegedly too soon, but how the seller handled the warranty issues related to the situation. If the counter people were accommodating, then the customer will probably return for other parts later on. If not, "customers have options they can exercise to their desires", regarding future purchases.
So, by observation, it's not specifically where the part is built, but what the CONTRACTOR wants to pay for or not pay for, in the way of material quality and projected failure rates. As for build quality, that can always be a little variable, but as one engineer allegedly stated one time (paraphrased), "IF we did our design correctly, if we threw the parts off of a 3rd floor balcony, by the time the parts hit the ground, they would have correctly assembled themselves." Be that as it may!
ONE thing I always liked about the Mopar Perf electronic ignition conversion kits was that they were all built to OEM production specs. Distributor, wiring harness, control boxes, etc. Which meant they were very good and durable. Perhaps that has been altered a bit in later years?
Just as it was 50+ years ago, the people in the auto repair trade usually know where to get the better parts. Whether from a dealership, a large auto supply, or variations thereof. Nothing's changed in that respect, by observation. Sometimes, it depends upon what the customer can afford to pay for! In getting the repair done or what parts are used in doing it.
Enjoy!
