Most of my rear wheels have the outer half shown here; I haven't been able to identify the manufacturer so I'm not sure I can get a direct replacement for the broken beadlock pictured. If anyone recognizes the "Lightning Bolt" logo and knows whether or not they're still in business I'd appreciate it if you 'd let me know. Another possibility (short of buying new wheel halves; I already know that's an option) is that another maker's beadlock rings may fit these rims; they're a 15-bolt pattern, approx. 12-1/4" centers. Weld are 14-bolt, Sander are 16; the only other 15-bolt rings I've seen are Keizer. If you're running Keizer 13" inch wheels and can get me the beadlock bolt center measurement that would also help me my decision-making process.
Thanks.
