Need quick help with driveshaft

I removed the universal joints on the rear driveshaft on my ZJ last night and when I started to re-install new u-joints today, I realized that I neglected to mark which end of the driveshaft that the slip yoke should be installed. Both ends of the driveshaft are weighted (one end has a couple of weights and the other has one). I don't believe that it will matter which end the slip yoke is mounted on, but I wanted to get other opinions.

NOTE: Transfer case: NP242 - Rear Axle: Dana 44.



Thanks for the help!
