Frame connectors

Factory added whats called torque boxes to convertibles and some others. They tie the frame horns to the rockers. About the same as full frame connectors, just not a straight line connection. Those would be welded in also.
Long ago, maybe in a different forum, a owner posted pics of distorted bolt holes where his bolt in frame connectors had moved. If my memory serves, he found this looking for a intermittent noise. I dont recall was this a race car or how long these connectors had been installed.
So whats a plan? Bolt in initially. When you're at a shop that welds mufflers, etc.., geter done.
