[strictlypersonl]

I've never used a Grant kit, but every other removable steering wheel setup that I've used has some play. Otherwise, it would be almost impossible to remove or replace the wheel.

It's all a bad compromise. The hex design makes it easy to put the wheel back on but seems to be the loosest. The finer the spline, the most likely the fit will be tight - but it's a real PITA to get the wheel back on in the same place.
