Would you run these axles?

THAT is an excellent suggestion! Thanks :thumbsup:
....depending on how hard the axles are (difficult to tap)
IF you can tap them, that's a good suggestion.
I would just use the 7 /16. Or find 1/2 studs with the same size knurl. (but I have one car with 3" long press-ins and two with screw-in studs in GOOD axles, Strange, and Summers Bros)
Yes, I would run those axles, but I would mount a naked rim, and check for runout (with a drum in place.)
I have only broken 7/16 studs under power on one car, a 55 Chevy with a rat, and a 400 turbo that shifted MUCH too hard.
