I replaced the cowbell horn with a 1940s look horn and the football air cleaner with a round chrome one like the 1940s bikes too. I have 1961 tank emblems, 1959 Cadillac tail lights, the chrome bag rails and front and rear fender trim.
Rat rod style pinstripping, DNA radial laced spoke wheels, the teardrop old school mirrors, and have some fender mods yet to be done to make it look even more old school.
