Open to sure grip

With help from others it is amazing what one can accomplish in their own garage, without having to pay others to do it.

Rob's measurements above are accurate, but, if you do check with a dial indicator it 'might' be a little wider due to wear. Just set it back to that setting.

The closer you can get it the better to eliminate the possibility of howling.

DON'T forget the sure grip additive.
