Just curious. This fender is on eBay now http://www.ebay.com/itm/322032279101, but I thought the 1956-up fenders just had a funny-shaped hole where the taillight wires went through. What does this fit?
Hmm looks like 56 and up "bobbed" style either factory or after market. I noticed no rivets also. Interesting one... 52 to part 53 had no rivets and Bullet tailight of course.
