My son and I are pulling the rear axles on our '66 C10 to do the wheel bearings. When I took off the rearend cover, the gears looked great, real good shape with no noticable wear, enough to make me wonder if someone had swapped out the original stump pulling gears with a better set for the highway. Hopefully they did, because we were going to do that anyway down the road. Is there any way to tell what the ratio is by looking at it? I don't know too much about gearing.....
If it makes any difference, its got the 4 speed manual with the granny gear.
