Part Name & Number

New here - I have a 2003 XE that's been very well maintained (57,000 miles). Having an issue finding a part and part number. Trying to find what's been referred to as the "link that connects transfer case cross shaft lever to shifter for 4WD" or "ball joint linkage." I've been unable to get a part number which has made it harder to source. I've been told if it breaks - 4 wheel won't be operational and trying to get rear main seal fixed but holding off should this part break during the seal repair. Any help is greatly appreciated.
