I was able to thread a bolt(6 x 1.0) that is about 1/2 inch longer and snug it up. I don't know what else is stripped out on this car (Seems a "Shade Tree" mechanic had his hands all over it and didn't know crap about it)
Glad that you had enough thread left in the hole to accommodate it.
I remember being so pleased with myself when I made it to the skill level that the dealerships were after at the time. But, after quite a few years and watching many skilled techs either retire or move to other professions, the stuff they are hiring to replace them has me worried.
