Hello All,
Any leads on halyard exit plates for a Charleston Spar mast? This plastic plate which broke on my mast needs replacement. The resource I have (Rig-Rite) charges just under $20 (plus shipping!) for this tiny piece of plastic and I can't bring myself to pay for that for this. Maybe it's hopeless, but worth a try.
Thank you!
