Anyone fit a 41/40 sprocket on a Azusa Astro wheel??

#1
So I'm trying to fit a # 41/40 sprocket on a Astro wheel, right now I was able to find a Trail horse hub that fits my wheel but can find a sprocket for its size I was thinking of getting a blank sprocket and getting the holes drilled... But before I do I want to ask for advise, any is appreciated
