Someone give up some good tips on how can I determine what rearend the old truck has. I know it has 10 bolts in the cover (if i didn't miss any under the grime) but that is about all I know at this point. It needs a heavy duty degreaser and some high H2o psi. Sounds like it is geared low when running thru the gears. Also if it's a posi track could I jack it up and roll one wheel clock wise and the other go ccw or does it work differently?
