Bear with me, this is my first build and I may not know what I am doing...I recently bought a project cart and it has three-bolt hubs with a 3" bolt pattern. I am finding it impossible to find a #35 sprocket (60 - 72 tooth) or appropriate universal sprocket carrier (for a split sprocket) to fit this pattern. Does anyone have any idea what I could get to fit or were I could find a sprocket for this hub?
