I can think of a zillion after market suppliers that carry similar bars. They wouldn't be America bars per say but would be very close if not identical. Drag Spec.,Vtwin, Custom Chrome, J&P Cycles, Bills HD, Etc.... 1" bars are very common and there are many choices. One word of caution is check width where they clamp and tou want knurling around the bar where it clamps and that needs to be spaced right. HD has same riser spacing as we do also the chrome doesn't last long on quite a few of the cheaper bars.
