time for an update...
Eaton Detroit Truetrac installation into the Nodular Iron Ford 9" third member.
This post has 3 "How To" videos that might help you decide if you want to tackle this upgrade.
Roy Teeter (co-owner of P.E.M. Racing in St. Clair, MO) assembled the third member and Truetrac. Highly recommended!
