Interlock Pins and Detents

The interlock pin goes in the 3-4 shift rail and prevents the transmission from shifting into two gears at once. Please do not run your toploader without the interlock pin.

You can use our shift rail id chart at http://www.davidkeetoploaders.com/shiftrailid.html to identify your shift rails and determine which interlock pin and detents you need.
