Replacing 67 Cuda front wheel studs - not so easy

Probably a little difficult to measure the vacant hole with a caliper? Have you tried? For that hub/drum I think I'd buy both oversized LH studs. If necessary you can make them the same length easier before pressing in. If the smaller knurl presses in too easy go with the larger one. I would think the remaining 4 studs should keep the drum in line.

Wanting all RH studs? Shouldn't be too difficult to find another drum/hub assembly with RH studs in it already. Call a few yards in you area.

Also a lot of folks have made the disk conversion from the 10" drums and may have the parts left over in a corner of their garage (lol, like me). Both of mine are rights...................
