Bigswingdaddy, you say find a 55-62 1/2 ton rear end. How much trouble would one form a 63 1/2 ton be? I'm working on a 47 1/2 ton using a 235 with a saganaw 4speed. Farmer down the road says I can have the one out of his old 63 that he says would run 60-65 all day. Kind of sounds like 3:55 or there abouts. I have not been able to look under it yet (snow drift) but would that year be good?
