Max-Torque will make one up. All we need to know is LH or RH threads, if it is a woodruff key (half moon), or full length keyway, verify what keyway width is, most are 1/8" but I have had people send me crank and it was 3/16". Lastly need to know what size sprocket you want to run from 9 tooth up to 25 teeth in the #35 chain. We can make them in #41 but then you are limited to a 10 tooth, a 13 or 14 tooth. Engagement will be 2,500 rpm or 3,000.
