I had to replace the back-up light switch, but when I went to replace it, I found that the other one had been JB welded in, and the threads were gone to replace it. Anyone have any ideas on a good fix. I though about getting a T-Handle B & M shifter with a 12v button on the side and then hooking it up to the reverse lights. Any other ideas??

 

Heli-coil the trans.

Realistic fix: Loctite Form-a-Thread. I've had good results with that in low stress applications. Clean everything up real good, it'll probably work real well there.
