I'm going to use this drawing I made to drill new holes in my drive sprocket in order to install it on a 68 spoke Micargi Puma wheel. center punch holes at the crosses. the other holes are the standard hole pattern that is drilled into the sprocket. I'll attach the file here. NOTE - forum wont let me post .dwg files, so I added the extension .pdf. just change .pdf to .dwg and hopefully it will work for you.
