drive shafts
 

could some one tell me what drive shaft options i have . i have swaped the 78 ford dana 44 and the 9" also have moved the rear 6" back and cant figure out what drive shafts to use. i still need to get the sye kit, but i would like to know in advace what i have to do.
thanks for any help. oh and its a 91 xj with the np231 inline 6.
this rig is just for off road.

With the jeep sitting level, take a measurement of center to center of your yokes. Take that measurement to a driveshaft shop and they will do the rest.

What u-joints do the axles take? Is it close to the XJ yoke size at all?
If you're doing an SYE then you'll need a rear slip-style driveshaft with a CV joint like an XJ stock front shaft. You could possibly use a modified XJ or ZJ front driveshaft if the u-joints are close.
