    I just put a 6" Superlift kit on my 78k5 and my splines are now showing on my driveshatfs, does anyone know how to measure for longer driveshafts or if the driveshafts from a longbed pickup will fit?

    measure the length of the slip out of the transfer case then jack up the back end (if possible) put it on jack stands now measure it thats the difference ussually you add 2" the shop that re does it should measure it for you.

    measure the length with the suspension flexed(maximum), and measure the length with the suspension all the way in. split the difference and that will give you a pretty good start on what you will be looking for in a drive shaft.

    Well, it kind of depends on what you are using the K-5 for and how much you flex it. Call Tom Woods and he can give you all the info you will ever need, and more if you want. I got both my shafts from him and have had no problems with them. Well except I crushed the rear one wheeling (thank god I bought the trail hazzard).

    Just curious, and maybe this is stupid but does anyone know of a way to find the spline location the driveshaft was supposed to be in?? I have vibrations attributed I think to drive shaft not being put back in the same place, and I'm hesitant (obviously) to try every combination.
    anyone?

    Mind if I interject?

    Just for grins I jacked up the front of my stock 88 this past weekend. Placed the top of the jack just in front of the middle of the sway-bar (on the frame). Lifted it 4.5 inches (slowly) watching the brake lines on each pump. (God, it's great to have a shop jack at home.)

    Anyway, the front shaft came about 1" out of the yolk. I measured it.

    So how much is left inside? really don't feel like taking it apart to find out, since I know most of you guys have the answer to this. Just curious...especially if this represented what effect a 4" lift might have on the front.

    (And yes I will SURELY need to get extended brake lines and/or relocate them.)
