I had two stripped threads on the engine block where the driver side motor mounts go. I decided to use heli-coil thread inserts kit, thread size for these bolts is m10x1.25 and you have to buy special drill bit I believe is 13/32 to use with this kit. Here's a picture before heli coil

Spray some kind of lube into drilling spot I use wd-40

Drilling the old threads out with the 13/32 drill bit make sure to cover things u don't want metal shaving on.

Clean the drill site out use break cleaner and compressed air.

After that use the heli coil insert tool to spin the thread insert in. do not spin in too far only till it passes the surface then spin the tool back out now you gotta knock the tab off, use compressed air to force the tab to fly out
