Yes.
Try FAB or Brownells & maybe even Marstar
I got mine from fab sports....around $35 delivered....it is an inch thicker so the original bottom screw( goes through bottom swivel) will not work ....the thread on the screw is a fine thread (weird size) so good luck trying to find a longer screw with that thread....i got another bolt and rethreaded the swivel threads to match it....I also ground down the head of the bolt and cut a notch in it so a flat tip screwdriver could tighten it....i dabbed some paint on the head of the bolt after grinding it down and cutting the notch....Overall it was an easy fix
