I was thinking 'that' but didn't want too go-there becuz of the 'wheel' issue. However, (I don't have 1/4" Heli-Coil data) the 1/4-28 heli-coil 'insert' tap size 'maybe' compatable w/restoration of the 1/4-28 stud...IDK!I've put heli coils in before. And they do have 5/16ths studs but then your going to have to drill out your wheels.
