Wellp, turns out there is a removable cover on the front, glued on. It was such a match in appearance with the main body of the wheel it looked like one piece. I did say I took a quick look at it. The cover was actually an aluminum disk. Had to punch a hole in it to get it off but so what.

Anyway, my strong armed 9 year old neighbor over rotated the steering snapping off the stop on the wheel and breaking off a tab on the shaft where it contacts the spring arm. I think I can make a metal collar to fix the spring arm problem. Anyone know where to get a replacement steering wheel?
