The maple nuts came as 4 inch squares, I cut 1 inch off of each corner and affixed them to the rear jaw with a couple of screws. The rear jaw is 7 inches high, and the right angle brace is about 1 3/4 inches thick and 3 inches wide. I used an old 1/4 inch beading plane to on the top of the rear jaw and the back of the right angle brace.
