Driveshaft Swap Question??????

I have a 1998 ZJ with Quadratrac and a new front driveshaft. Will the drive shaft fit my 2000 XJ with Command Trac? Thanks for any help!

the only thing you need to do is measure the length. the u-joints and yokes are the same

Everything will bolt up fine, the U joints are a 1310 in both. Length is your concern. Remove both, place each side by side and see how far off they are. You might get lucky. You shouldn't need to swap yokes, just the shaft.
