I’m not 100% sure on the big bolt fenders from the photo, but the regular sized fenders have that flat area on the opening arc where the fender brace bolts on. It is apparent in the little trucks, but the big bolts seem, to me at least, to have a better arc without that flat spot near the front.
Those flat spots would be at 10 o’clock on the LH side, and 2 on the RH.
Does this help?
