Lakewood J Bolt Traction Bars

[Chuck_Burg]

Hi guys. I recently picked up this set of J bolt traction bars. I bought them on eBay. I got a good deal on them and figured I'd buy them based on their condition alone. They're not like other Lakewood bars I own that use a triangular bracket on the bottom of the bar for the "Stirrup" to connect the J Bolt. These have a welded bracket which eliminates the "Stirrup".

The seller claims to have bought these in the early 70s and barely used them, recently bead blasted them, powder coated them, replated the hardeware, and added the stickers.

They look a lot like new Competition Engineering bars powder coated yellow. Any thoughts as to what they may be?
