This fitting is for the fixed intermediate backstay tang on our mast. It's for a swaged wire end (of some sort - maybe a T, maybe a stem ball?). It's not rod rigging. It sort of looks like Navtec's K200 external stemball tang? Anyway I want to change the mast fitting to something like a Navtec rope eye below for proper Spectra running backstays. Something with more articulation than this fitting, so I can take the runners aft. Right now this will bind if it's more than a few degrees past mast centerline.
