T-RUCK,

The 6207 is a common metric bearing. 35mm X 72mm X 17mm wide. Retails for about $10.00 anywhere. The numbers marked on the race sure seem like some GM number, but I haven't a clue if they are or where this bearing would go! For ten bucks, I wouldn't put much energy into it. smile

I wonder if your bearing has external snap ring grooves?
