I forgot that I have 2 of these. One is 9/16 -5/8 and the other is 11/32 - 3/4. So never look just grab both and use what fits. Silly me. I did manage one fine day in my youth to create one. Used a Fo%$ damper pulley nut with the wrench placed against the frame. Starter motor did the bending. Should have seen the look I got from the counter guy at Sears. I am not a big guy(150 and 5 ft 7) at the time). My buddy who went with me was 6 ft 5 and well over 300 so I just hooked a thumb over my shoulder and got a new wrench. smile
