As some previous posters have said the first thing I would do is try getting a die on it to see what you end up with. That will determine your decision going forward. If that does not work maybe a different box. You can rebuild yours if you have a donor box to rob the shaft. I would not drill and tap the center of the shaft.

Steering wheel pullers are cheap and the photos show what happens when you do not use one. I used a harmonic balancer puller as they seem to be a little more heavy duty. The puller I use has a flat attachment on the end which is larger. I back the nut of the steering wheel flush to the threads and put a penney on top of it ( if I have one ) . Tighten everything up and smack the puller shaft with a hammer. Usually is all it takes. One can fight you and then next falls off.
