i have a round bar distribution hitch and i replaced the frame mount chain hangers as the ones that came with the hitch were broken.. The issue im having is the new hangers are 4" wide and they are interfering with the battery location. I have been trying to find the narrower 2" ones that used to come with the hitches and they seem to be hard to find and when you do they are over $100 a pc. For that price i would be better off trying to find another used hitch with the mounts im looking for. Any ideas where i could find the narrow ones for a decent price..
