I ended up ordering a set from this guy:
https://www.cheapjeepoffroad.com/weld-on-bead-locks
Basic 15" rings are $145. My 16s were $160.
$55 for hardware and $20 for powdercoat put me at $235 total.
Shipping was harsh, $55. I really wish I'd planned better, we were just at Haspin last week, and the guy is only 20 minutes from there. I could have picked them up.
Will update once they've been received and installed.
