All, - the original front drums are of a different construction than the replacements (AFAIK anyway). The originals have a rather thin "center", which is swedged to the hub via the wheel studs. Replacements (at least the ones I have seen & used) are all "cast-iron" (vs the "sheet-metal-looking" center of the original), and are much thicker in the hub/stud area. This prevents "re-swedging" - even if you *could* get new (correct) studs. However, since the hub is what actually "centers" the drum, and the wheel will surely keep the drum from falling off, it makes no difference, and what you end up with is a drum that can be "slid" off the hub - just like a rear drum on 65 & later models. So, I would think that as long as you can *get* a replacement drum, don't worry about the wheel studs & swedging, all you need to know is that the center is the correct size for the hub. I put these replacement "thick" drums on my race car (67 Belvedere) years ago - a necessity due to the use (required) of extra-long wheel studs. No problems ever, and made for quick inspection of the shoes. Regards, DaveG.
