So perhaps this glue failure issue was a non-issue back in 1969? Is it possible the riveted rims was just a running production improvement that occurred by a natural improvement process, not because there were rims coming apart?
I don't see a new suffix part number for the riveted rims, versus non-riveted rims. Although, I am not sure that matters one way or the other to the recall. It makes sense that if the chamfer or hole recall caused the rims to get replaced, and that a running production change to the rims occurred adding rivets, then it makes sense that owners had their rims replaced under the U-01 recall with riveted rims. That could be a coincidence because no non-riveted rims were left or available.
I'm trying to determine if running glued rims is actually an issue or urban legend. I'm sure there are several other '69 Shelby owners still running on glued wheels like I am. It would be helpful to know if that is actually a safety issue or not. Since nobody has the recall document, it is hard to know for sure.
