    Hey, there is a guy selling a 68 C20 4X4 nearby, I havent seen it but wanted to know what kind of equpiment was slung under these classic rigs. He bosts a 4" lift and 33's. What kind of axles, trans and x-cases were put in it. I know everything could be swapped out for later model pieces but for the price Im looking at Im guessing its original.

    Thanks in advance

    The axles should be a Dana 44 for the front, and an Eaton full floater in the back. Being a 68, the front axle probably has drum brakes and closed knuckles. As for the transmission and transfercase, if it's a manual it will be a SM-465 with a NP205.

    I think it's the SM-460 not the SM-465 in the early trucks.

    When I first bought my 72' 3/4, it had "custom 20" emblems on the side. However, in the VIN number it had a "K" which means fourwheel drive. I think it just comes down to the fact that some people don't put the right information in classified ads.

    Thats what it means. It should say something like "C / 20" on it.

    It probably has a SM-420 tranny and Rockwell T-221 T-case.

    "C"= Conventional
    "K"= Fourwheel drive
    The above is true in regards to a VIN number, which is not nesscarly true for what the side emblems say. As metioned earlier, the "C" on the emblems stood for "custom." Also, GM stopped putting the SM-420 in their trucks in 67'. Leaving the SM-465 as the only other possiblity.
