    As far as GM versions go The first year or two had a thicker passenger side top spring cap/cover that was cast iron instead of stamped steel - other than that the "fat" axles started in around 1979 and continued until the end in 1991 . Basically if you address the axle thickness issue all GM versions are created equal .

    I think the knuckles on the newer ones have a higher tierod mounting location
    I know that my dodge version does
    also the axles can be neck down in the old ones vs fat in the new IIRC

    Ok so 85 and up are the best. So the 79 60 is a little weaker? Is there a big differnce?

    If you upgrade to 35 spline stubs with flages, and run a 84 and prior Dana 60 the next thing to break will probably be your innershaft. If you have the 85 and up shafts and 35 spline outers, the next thing to break will be your u joints.

    Either way 'sumthin' is breakin' but id MUCH rather not break an inner shaft and but a worse shock load on my detroit.
