    Stephen, I have a 77 Blazer w/14bff, np 205, D60, I just installed a shackle flip kit, I have 6 in lift, do I need to do t-case drop?

    if your 205 is fixed yoke...and you have drive shafts that can operate at decent angles...I dont see why. Oughta be able to keep the tcase tucked up nice and high.

    doh, a fate worse than death!!! I have a slip yoke myself and have had some kind of vibe prob ever since I lifted 4". i am in the process of swapping in a fixed-yoke np205. Add some high angle drivelines, and everything should be a-ok, even with the tcase up high. If u wanna keep the slip, drop the case.

    I'd measure up the angles and see what you have. No matter what, the flatter the driveshaft is the better of you are. Less angle will always improve the ujoint life. Whether that's worth it or not is up to you to decide. You'll give up a little center clearance for the joint life.
    Personally, I'd look into a cv jointed driveshaft for it even though you have a fairly short drivetrain. I wasn't ever able to really get mine sorted out with 4-5" of lift so I don't have a lot of faith in getting them to work perfectly without a CV.

    yeah, I dunno how many fellow ck5-ers I have seen that have beat their heads against that wall...I know I have. All kinds of shimming, tcase dropping, drive shaft lengthening/shortening etc etc...better off to just get a tcase that has a fixed yoke output and then use a nice cv shaft on it. Save ya a LOT of head aches...

    Thankx, I want a fixed yoke, but I didn`t think it was in my budget, I guess it is time to bite the bullet and look for a fixed yoke!
