Why do you need the beadlocks? You should be able to find regular 16.5 inch steel wheels pretty cheap.
Go for a ride with me and you will see why I want the bead locks

I can get them for about $150 each. But somebody may be on here that can get them cheaper. As they up armor them they are changing from 12 to 24 bolt. So some 12's could be laying around somewhere

I have them and run mine on regular 16.5 rims, and when I say the have seen hell its an understatement lol.
If you feel you need beadlocks that's fine but mine have been through plenty of tourture tests and done fine, and I'd you are running bias ply be prepared for them to wear down fast, if you are putting them on the diesel you posted about buying not too long ago that is
