Great to know; thanks!
With that in mind, the Classic Locks are street-legal fakes for the beadlock look. The Mickey Thompson rep told me that they do not make any true beadlock rims, so *any* MT with the bolts on the sides are their Classic Locks.
The bolt ring is a separate thing, and can be swapped out for others anodized in various colors. They are held on via (I think - this may have changed over the years) eight real bolts. The remaining ones are just bolted onto the ring. The fake ones have MT on the head and the real ones are blank — again, according to the rep. (I will confirm this against the rims on my TJ and if what I have differs I will post that.) The short "fake" bolts are not something you can replace with anything from a nut and bolt shop or at Home Depot. But any MT dealer can get them for you easily.
The rep told me to look at the rear of the spokes to find the size information. It is indeed there, very clearly cast into the aluminum, along with max load, etc. They run wide, as mine are officially 15x10s but measure exactly 11" across using a straight edge on each side and a tape measure through one of the holes.
I hope this ends up being helpful to someone in the future.
