A couple of my Road Wheel centers have stripped threads. You can usually give the center a turn and use some alternate holes, but some ham fisted tire changer in the car's past made sure that wasn't going to happen. So... A repair was needed.
Typical stripped hole.
First, you'll need a Heli-Coil kit. The threads are 1/4-20.

Included in the kit is the special Heli-Coil tap, an inserting tool and 12 heli-coils.
You'll need some drills, tap wrench, small punch, small hammer, and an electric drill. A countersink bit, like shown is nice but not a must.
I used my trusty Craftsman hand drill. Having a variable speed and easy reversibility is handy.
The proper size tap drill is a 17/64".
Because of the type of material, I first used a 15/64", then a 1/4" and then finished with the 17/64". The material that they cast the wheel centers from will tend to grab the drill so you want to "sneak up" on it to get the hole drilled to size.
