Yup, I have that article
I like the oddities;
Then combine the fact that everyone who drove a Muncie three speed musclecar seems to swear that they have the perfect gear spread, with their cast iron design, they're apparently near bullet-proof - I would hope that the car in no disappointment when I have it done.
Btw, iirc that car wasn't quite bare-bones, but rather a nicely opted car where it was speculated that the original purchaser might have thought that the L74 option would have netted a four speed transmission...
I know a local collector who has a '70 M13 equipped Judge - not even he knew that his car had a Muncie three speed (he thought it was a saginaw!?).
Time, and (God willing) a visit to the PSMCD's will attest to if it's better than your average M20 equipped Formula.
