Is there a hardware solution to this problem or should I refer this to a body shop? The threads to the hole of where the rear hatch strut bolts in are damaged, hole is wallered out. Can’t access the back side of the hole as the c pillar is a sealed panel.

Use a nut sert/rivnut. Basically a thread insert that goes in like a pop rivet

If there is room behind the panel I'd use a Jack Nut, it basically works like a pop-rivet but gives you a threaded insert that gets "mushroomed" behind the panel. They are available in metric and SAE threads. Here's an example of how they work: youtu​.​be/fdnuMrTyXAo?t…

A riv nut looks to be the best solution here. A jack nut will also work but I don't know how strong they are in comparison.

Benjamin: You could take a piece of plate,drill and tap it and drop it down on a wire through the opening for the wiring harness. I'm thinking like making your own striker plate mount. Might have to "waller" the rest of the hole out. If not comfortable doing this kind of work then by al-rights send it to a body shop, at least then they will be able to do a paint match.

This is what we have used in the past amazon​.​com/gp/product/B07…; It's relatively inexpensive and works well

Hi Benjamin. Looking at the damage to the hole from the previously loose fastener, there is nothing remaining that is flat and of a good shape to provide a surface to clamp to. I also do not believe that a Riv Nut or similar will result in a lasting repair. While the second layer of steel that serves as a reinforcement hasn't broken away, the surface where a clamp load needs to be applied is…

Thank you for all the suggestions and the time you took out of your day to help me! The reason why the failure I believe was the strut ball joint/bolt had loosened up and backed out of the threads over the years and the factory quarter panel threads couldn't handle the stresses of the unsecured fastener, prying side to side every time the hatch opened and closed. I've been a dealer line tech my…
