M37 Ignition Wires

I have a conundrum for you guys. I would appreciate having some info to chew over on the weekend.


'52 M37 with the 24v system and generator.

My old ignition wires are more electrical tape than rubber. I'm junking them.

New sets are unbelievably expensive. About the cost of a 12v conversion itself.

So I stumbled across the MSeriesRebuild set that they offer on a facebook post. I contacted Charles about buying a set. The email process is like pulling teeth. Gave up trying to get a price on an exhaust system after months of waiting- but the ignition wire set seemed like a slick solution to a problem at about half the price. Still the most expensive ignition wire set I've ever seen and I work at a car restoration shop. Thought I'd seen it all.

So, wire set arrives. Civilian plug end. Nice, nice. Got my civilian champion plugs installed already. Perfect. Distributor ends are unfinished. Just rubber boots and a healthy length of ignition wire insulation hanging out waiting for an end. I checked the box again hoping to find a bag of terminals to crimp on, or some kind of instruction sheet, hand written note or even cave painting to describe what to do next. I assumed for the still ridiculously high price that it would be a complete set of adapter wires with screw on/spring terminal military terminals on one end and 90 degree boots for a civvy plug on the other.

My fault, I assumed for the price and by the description that the wire set was made for the application with no further work needed. Apparently you need to make the dizzy wire ends up yourself. Not opposed to it, just...if I have to make and end, I might as well make the other, in which case I should have just bought the wire and jacketing and cut my own for a third of the price. But, I've spent the money and I'm committed now. I sent Charles an email with my query but since its after hours on a Friday, I have days to wait and the wires won't be installed this weekend like I hoped. So I'm here not to bash Charles, nor whine about my woes. I'm simply after food for thought.

So I do some reading on the G741 forum and poke around a few old Mopar forums about the situation.

Found a post from 2016 on G741.org where the first option is to just strip the ends and fold the conductor back up over the insulation, stuff it in the distributor tower with a layer of electrical tape to fit the wire insulation tightly and roll the rubber boot over the tower threads to make a seal. Makes sense. But to be thorough, I read further and Charles himself states that it works in a pinch but isn't recommended in the long term. THREAD HERE: http://www.g741.org/PHPBB/viewtopic.php?t=7884

Charles mentions the "right way" to do it is to find the ends that allow you to "snap" them into the inner cap towers. I eagerly scrolled through the thread hoping the eventual part number would come up, but the thread is a waste of time from there down as series of backtracks and excuses follow and the thread ends unresolved with the OP now just shaken in his belief that his mod isn't going to hold up long term.

So, has anybody here modified a civilian plug wire to "snap" into the inner cap towers? If so, what part numbers did you use?

If not, has anybody found a source for 24v wire end parts and have any info on how to make the original style terminations?

Thanks in advance for any and all help.

Honestly I have had reasonable luck just stuffing the wire in the cap by folding the wire core back a bit on the insulation. Goes without saying this does not work with resistor core wires.
