Replaced the rollers with 7.50 michelin XZYs on 1 ton rims. It already looks better and sits nice and even. Did a little bit of cleaning and checking out what all was piled in the truck. Lots of nice original features remain. First up after more cleaning will be brake system rebuild with a combination of series III parts and some Ford bits and sourcing a transmission, t-case, and rear driveshaft.
