As I stood by my KK talking with Dennis and I looked for those spot welds, there were none. Apparently it came down to the year of manufacture, that's all, other than that removal with a Dremel cutting wheel would make easy work of any tack weld as you stated. Looking at your break, I'd call that an oddity. For moi, it's pretty straight forward to install, remove the two cap nuts and replace. Weird how it happened though, I opened to take a temp on the meat and the latch stayed in my hand. I said, "this ain't good." So I posted this for those unaware to be mindful of the possibilities, reassure them it's only a speedbump. That's all Folks
