I bought the tool from Proform. The holes for the bolts were off a litle. I drilled a slightly larger hole. My problem is that my big fingers can't seem to get the keepers installed. I took a pair of needle nose pliers and gound a groove so the keeper would stay in the pliers. That got the first half in but I can't seem to get the second half in place. I need a mechanic with thin fingers. Getting old is not for sissies. Tarnished not Golden years.
