Bonneville America Forums Forums Technical Forums Performance Mods socket to remove and replace counter sprocket

A well stocked Sears tool department is probably your best bet. If they don't have a 36mm, you can get by with a 1 7/16" socket. Others have had luck at Autoparts store. This size is used for axle nut removal on GMs and Fords.
