these are very high end reproductions of the original chrome clamp on headlight ears used on the first year 70-71 US90s to be able to mount a headlight to the forks , these are identical to oem in every way

NOTE !!   these are sold in Pairs and you must remove the top plate on the forks and slide them down from the top to install if you try to spread the clamp to go around the fork it will be damaged
