Mistral Mast Track Pulley

This Pulley is used on both ends of all Mistral Mast Tracks since the early 80's until 2006 when Mistral switched to the Cobra Track or the thermometer track (this track has black plastic on both ends).   If your Mistral Mast Track has white plastic ends this is the pulley for it.  Use a dry lubricant on the pulley to increase the life of it.
