I thought I'd clamp them in a vise & file out the Whizzer arm to fit the spline shaft on the Shimano hub. I did that to a Harley sprocket years ago because I wanted lower gearing than was available. Well, this Whizzer coaster brake arm was hard steel. Real hard. So I heated it with a little propane torch & let it sit overnight & the next day it filed easy. Now my Bike has the Shimano hub & brake lights.
