ok guys the news isnt good. i went to fastenal and masterbolt in my town without success. they have never seen the style of bolt and had no idea were to get them . i went to a machine shop and they can make the bolt from a grade 8 bolt measure and reduce the shank and drill the center hole but cant tell me if the torque will break at more than 15 ft/lbs until 1 is made and tried. minimum order 100 bolts! ballpark figure is about 6$ per bolt.
so for now i have not succeded in finding a replacement. sorry guys
my only other thought was maybe a m/b mechanic can find the bolts in their shop. i cant believe they dont have spare bolts .
