The 2 identical black plastic parts to which the the clevis pins of the rudder attach on a Hunter 26. Where would one buy those? I'd like to get 'em as spares since they are made of plastic and UV is degrading them...Also, I can't find long enough clevis pins of the right diameter. 3/16" x 3" or 3 1/4" Any source for those? Searched everywhere...Many thanks.
