    I know all of you have done a 1/2 to 3/4 conversion. My 20 is gonna be a 10 and Im wondering about drive shafts/u joints/yolks and rear sway bars. I guess tips for either conversion are helpful. Front sus questions will come later.

    The man with the most tools when he dies, wins.

    Thanks

    Why goof with swapping the entire rear end? Easiest thing to do is probably to swap out the gears in your current rear end (probably 4:10 or something similar) for something similar to a C10 (3:27, or something more driveable). Then remove the 2 overload springs which will lower the rear end a bit, and soften the ride. Pretty much everything else can stay the same. Viola - instant C10.

    The only crummy part is you'll probably still have the 8-lug hubs, but those can be replaced with new or pick up a set at your local junk yard.

    Which rear-end do you currently have? The Dana's are somewhat desirable, keeping it might be a good thing.

    Just my 2-bits. Good luck whichever option you choose.

    Thanks for the reply. I did swap the whole rear end. Only a couple of minor problems: The u joint is bigger on the 20, but they make a universal with both size bearings for the conversion, and the panhard bars are different sizes and mounts. I cut off the 20 rear end mount and welded it to the 10.

    Taking a second look. I think the panhard bars mounts on the frame are identicle from the 10 to the 20.
