Driveshaft binding

[pedigo78]

So my 85 k20 front driveshaft is binding just a little. I was under the truck doing some work and decided to rotate the shaft, and saw that it hit the yoke on the transfer case. (this is my front shaft) my transfer is a np205, so do i need a clocking plate, or what

How much lift do you have?  If the driveshaft is at such an angle that it's hitting the yoke, you're likely to trash it off road.

Does the front driveshaft have a constant velocity or double cardan joint at the transfer case? If not, a CV front shaft may gain you a little bit of extra clearance.
You can spacer the rear crossmember to gain a little bit more room.  If you drop the crossmember, you have to be careful to make sure you don't jam the engine distributor against the firewall and that the whole crossmember setup is sufficiently supported (heavy duty hardware, steel spacers and the like)

Those are a couple thoughts off the top of my head.  I'm sure others out there have some good ideas.

     x2, need more info to be able to help.  If it binds while on the ground and not flexing, then you do have a big problem.

if you can rotate the shaft its not binding, it may appear to be touching but the clearance on some parts is very small. with only 4" lift your good i have 6" and dont need any clocking plate
