Thanks, Coy!!! I appreciate your doing his for me!!! The late 60s bracket spacing is the same as the new Ludwig I believe.David I measured a late 60's bracket (with the eye bolt) at 1 7/8" center hole to center hole and my WFL spring loaded FT bracket (Clipper) at 2 1/4" center hole to center hole. So, no they don't match but I'm not sure about a new Ludwig bracket hole spacing. Hope this helps.
