I fixed the same problem on a 96 Chrysler car with a steel threaded insert from the hardware store. It looked like a tube with threads on the exterior and interor and a screwdriver slot for seating it. It's not a helicoil. You just have to ream out the stripped hole and run a tap into it, but not all the way as you want some partially cut threads to provide grip for the insert; the threaded insert is screwed in with permanent Locktite. The insert provides new threads. That repair is still on the road...

Bob, if drilling a new hole freehand with a power drill, it's easy enough to put it in crooked. This is not the case with your situation.

With reaming out an existing hole a tad larger, the drill wlll follow the existing hole and be in alignment, unless you intentionally lean on the drill sideways to make the hole cocked off center. Then comes the tap. Tapping a hole by hand the tap will automatically align with the hole, even more so than the drill-- in otherwords putting in that threaded insert is a piece of cake.
