If the pin is worn, replace the pin. If the fitting is worn, which is likely as it's the softer material, fit a bushing top and bottom. There's plenty of beef left on the fitting by the looks of it, no need to replace the whole thing.
On our boat, the fitting for the gooseneck toggle and the rodkicker were identical. In the Selden catalogue the number is clearly listed for the gooseneck though.
