    Hallo,

    i want to swap in a 14bolt ff and a dana 60 axle in my stock 1979 k5.
    I checked out that the U-joint at the stock front driveshaft works with the Dana 60 yoke.
    But the problem i have is, the 14bolt ff yoke will not match the stock rear driveshaft U-joint. the 14 bolt yoke is bigger.
    I figured out that there is a special U-joint available wich fits the stock driveshaft at the one hand and the bigger 14 bolt ff on the other Hand at the same time.
    I don´t want to cut and weld on my stock driveshaft.

    Which company makes and sells these special U-joints ??
    TRW Federal Mogul Napco or something else?

    NAPA #348 if your driveshaft yoke uses external C-clips. #447 if it uses internal C-clips. /forums/images/graemlins/thumb.gif
