Default Leaf spring mounting bracket threads

Pulled the front leaf to facilitate oil pan removal. In the process, the leaf bracket to cradle bolt hole seems cross threaded. Must of happened by me incorrectly unbolting brackets under load. Going to bye a tap and die, chase the threads and hope for the best.

the leaf spring is curved and under a lot of stress even lifted off of the ground. I don't use the GM tool, but you really need to compress the spring to remove the bolts without damage

I'd buy a new cradle and swap it if necessary. I have a collection of them, especially

A couple of mine stripped out. I used Time-serts to fix them.
