Do I have to take off driveshaft to move t case and tran to get clutch
Hi and welcome to CB.com!!
Yes, you need to remove the driveshaft. At least disconnect it from the transfer case. but with only 8 bolts/nuts, it's a pretty minor task to remove it completely and give yourself extra room underneath. Assuming the transfer case end has a CV joint there's 4 bolts into the transfer case yoke. On the differential end there should be 2 u-bolts holding the u-joint caps to the yoke. Be careful when removing the differential end u-joint as those u-joint caps will fall off. After removing, rap some tape around the u-joint to hold the caps in place.
