Had some driveline issues a couple weeks ago down at St Gen county truck pulls. We slid the ol dinosaur in to Update transfercase we went to a 271 case out of a Superduty Ford and drop some Driveshafts off over at Dirty Birds Driveshafts to get adjusted for us. Now we will be running bigger u joints in our drivelines with flanges and hopefully start to see progress with it. This is a cool upgrade that is fairly cheap that all OBS fords could use. If everything works right well have everything back together to head to Jefferson County fairgrounds this weekend. If not well have it out next Saturday for St Francois county truck pull
