Redfish, Are you saying, the allen head plug, with the center drilled out and tapped should work, or the easy out i installed should work you mean??

Helicoils will work and they are recommended in factory service manuals for places like the flexplate to torque converter bolts.
I'm saying handmade hole bushings will work too. We didn't have helicoils on hand for every application so a handmade 1/2-20 to 1/4-20 bushing for example was the only option.
