Well, if you are lucky, it's drilled for a bushing. That solves that. The two or three I've messed with that had 4 speeds weren't. Bearing pilots are better in my opinion anyway. Perhaps you have a crank ready for bushing. I've never been that lucky.
Ok. I've just heard that they can eat your input shaft if not properly aligned. I ordered a bushing from my auto parts store so I'll go pick that up tomorow
