Taking the advice from Gulf Hunter and am in the process of upgrading the cheap bolt assembly for the coil ears and lower shaft from the stock 1/4" x 2" commercial grade (6/6 nylon) black bolt and wing nut to a custom made unit (from www.craftechind.com) which is a 5/16" x 2.5" super strong nylon with 30% fiberglass filled, black, Knurled Thumb Screw with matching Knurled Thumb Nut for the other side. Of course, you will need to drill out the coil ears and shaft opening slightly to accommodate the extra 1/16". As a FYI, KellyCo quoted $8.95 for the stock cheap crap replacement - bolt and wing nut. I had to buy 25 sets of this for the custom run, so if anyone is interested I can send some out at my cost which was about $8.00 for each set with postage. Should arrive in about 10 days. Let me know if interested. Thanks again Gulf Hunter for the great advice.
