Thanks for your help with my problem.
The pivot bar #26-129 (third picture) is correct. The pivot shoe #15-152 (first picture on right) is incorrect, the one on the left is the one I am trying to replace. Size is good except 17/32 thick would be best. The second picture is the old one, note the receiver accepts the flanged end of the pivot bar. I would like to return (5) of the 15-152 pivot shoes and get (5) correct ones.
