Kevin,

I now see what your up to...... The freewheel I'm sending you is an Ultra spaced freewheel, and will NOT index with Accu Shift levers,it will however index with Shimano 7 or 8 speed levers, and Shimano derailleur.... You would use the limit screw on the derailleur to stop the shifter from going into the 7th or 8th speed. Shimano and old Suntour Ultra freewheels have 5.0mm spacing cog to cog. Your all set if you want to go index or friction. Yikes.......
