Here's something I did in my automotive days yrs ago: apply a medium coat of JB Weld-type epoxy to the clean bad threads. Wrap a layer of Teflon tape ("Plumbers tape") around the threads of the bolt leaving NO exposed metal. Gently screw the bolt in while the epoxy is still WET. After 12-24 hrs unscrew the bolt and remove the Teflon tape, reinsert the bolt and 'listen to the music' !i!
Another option is using a TIME-SERT - which is far far stronger than a heli-coil.
