1st gen double cardan joint

Hey yall so tried replacing a u joint in the double cardan joint in my rear drive shaft it's a 02 extended cab 4wd thot it was just to u joints but in my rush and the cold once i got it half way apart I realized it there is another part in the center of it was able to match up a new u joint cause theres no listings anywhere for the u joints or the ball in the center I've found threads saying i gotta buy a hole new driveshaft others saying they rebuilt theres but no one lists any part numbers for the u joints or the ball in the center idk if jeep is the same? If someone can either send me a link to a thread that has the part numbers or give me the part numbers so I can order them cause the noise and vibration is driving me nuts and it's my only vehicle at the moment it needs to run thank u all

 

I have a drive shaft shop rebuild those things.

I know they can source the parts but have no clue
