Hey Ken, if the holes are toast--put a thread repair called Keenserts in

to

repair them. I've used these for 20 years instead of the Helicoil typr.

Check

 Keenserts are probably better, in that they are solid and not a spring

however they require more meat in the are of question, as they have to be
