Divorced Rockwell T221 transfer case with 3 drive shafts. Has a slip joint on each drive shaft. No Cardan joints. What direction is the slip joint on the front driveshaft? Mine had the front drive shaft slip joint on the front near the axle, but I've seen a couple of pictures of restored K1000 or K10 with the slip joint toward the rear. I've seen time period 4WD GMC or Chevrolet brochures that show the slip joint installed both to front and rear.

I asked a drive shaft shop today and the two guys at the counter said joint to the front. One said more debris would enter the joint if toward the rear, the other said lighter smaller sliding yoke to front will move more easily with the axle than entire drive shaft having to move with bumps if slip joint was to rear. By the latter logic the rear drive shaft should have the slip joint at the rear and I don't think I've ever seen that.
