Flexplate orientation/Transmission to engine mounting?

Seems drilling and tapping two holes in that bushing would be easy. Then just use a puller.
Great idea.
I ordered that Lisle 55600 tool. Should be here tomorrow. If it doesn't work I'll try the drill method. The Lisle website says it's for brass and bronze bushings not steel. I'm pretty sure the bushing is cast iron so hopefully it'll be able to bite a few threads.
