^This. Try and find one that the dealerships use too, since you can often organise to catch them on the way back from another job (as they're always out and about fixing up f*ckups from apprentices) and thus avoid the call-out fee... We get thread repair guys to my dealership all the time, unfortunately u will still have to pay call out fee.. Getting bolts out and repairing threads puts food on his table for his kids ! I must have jagged a good one then. Snapped a bolt on the water outlet on the end of the head on a 4AGE, thread doctor who works for the dealerships in the area came by on the way home from a run, drilled out the old bolt (with a wonderful 90-degree drill, which was awesome considering it'd be next to impossible to get a standard cordless into the area), bored and heli-coiled the bottom hole and re-tapped the top hole, all for a measly $70 including labour, which would have been about 1/2-3/4hr. Some of the tools and ideas they pull out of their hat aye
