Re: Pertronix With Original Pop Out Switch….

Original pop out, No. It just wouldn't be practical. Modern switch that has a pop out feature, yes but it should be switching the power line to the hot side of the coil and not the hall effect module...

Of the Nash Metro ring & pinion sets on flea-pay, the tallest one is 4.22:1 but they are pretty small. Kits to change to 3.90:1 are available.

Re: Model T Ring gear,

Ring and pinion gears are generally always made as a matched set. To find a ring that will match some other pinion design is a lot worse than looking for a needle in a haystack.

Re: Wanted axle ends

The later 37 to 41 axles are wide enough that a Model T spring or a Model A spring with reverse eyes can be used but some use other springs. I would be more worried about having only two bolts...
