I’ve got a set of NW Treads with broken clips on the end through which the OB pins are set when they put in place. Somewhere along the road they were flattened and cracked in spot and are beyond repair. A whole lot of years back someone was selling repros of these as I did once have to replace one (and still have the second from that set. But it was a long time ago. Does anyone know of a source of repros for these clips?
