Birth of a 1970 Dart Convertible

The pic that has the cutout hole piece screwed to the 2 x 6? Did you screw the board to it to keep the hole saw pilot bit running straight? I wish I had done something like that when I bored the hole in my truck bed to install the B&W Turnover Ball hitch. It was hard to keep the hole saw running straight, and it wallowed a tiny bit on me! :BangHead:
