As far as I know, the torque ball housing bolt pattern hasn't changed in years, more like decades, so it will still work with the newly enlarged hole. Surely there is a machine shop close by you can trust to enlarge the motorplate hole, or not! I can do it in my shop, but we're many miles apart. If you have the crank out, that would be an option, but if you do the motorplate, then the next time you won't have that problem! Just sayin! Bob
