The 202 bolt was also used for the inner fender-to-fender attachment around the wheel opening, and my untouched originals do NOT have any "points" or serrations on the conical washer. There were about seven different variations of 5/16" captured-washer bolts used on the front sheet metal in various locations, and line repairmen used whatever worked at 57 per hour when one was missing. The AIM is correct.
