So I have my eye on a set of Cragar 352 series black steel simulated beadlock wheels on Craigslist for a reasonable used price. The problem is the fake beadlocks are rusted out. I don't care so much about the quality of these wheels as they are to be used only in the winter and will see lots of salt. Is it possible to replace the bolts on the edge of the wheel? If so, what size are they?
