Pro Body Tool II: Without a drill press, it’s nearly impossible to drill new axle holes. Not every race allows you to change the location of the axle holes, but if you are allowed, it’s easy to add stability to your car by extending the wheel base. The Pro Body Tool II fits exactly around the car block and helps you align the holes and drill straight axle holes with a hand-held drill. There is no way I would try to drill new axle holes without this tool, even if I had a drill press. This tool makes it simple.

The metal tool comes with the required #44 drill bit. Suggested retail $11.95.
