I saw that too. Crazy it’s from 2006 and still having the problem in 2025.

They stripped before I could get a torque wrench on them. The originals I cleaned and put back torqued to 25ft/lbs with no issue.

Are yours the CIP clips or other? Where did you get them?

Not sure the brand. I can look closer tonight. They came with the install kit from Eaton Spring

Honestly, I could have sworn my 67 originals were the barrel style but could be mistaken.

AMK fastener sold them at one time.

The original clip nuts on my '67 Feb LOS built are hex. I have a set of the replacements from OER and the bolt seems under-size, as it wobbles in the barrel and the threads are shallow in the barrel as well. I can see where they aren't going to hold much torque.
One of my original bolts cross threaded in a nut too and the bolt is trash. I was going to use 1 replacement clip nut and bolt, but not now. I will re-thread the nut, but will need a bolt, as the replacement bolt is loose in the original nuts too.

There is no brand identifier on the j clips
