Kelly,
I'll say this much. There's been a few times when others have posted errors or peculiarities with Service Manual illustrations. Sometimes the images are borrowed from earlier vehicles or may have been manipulated or altered.
I'd think the most important thing is are the forks oriented correctly. I've not spent a whole lot of time on the transfer case rebuild guide but know there was a lot of collaboration on the transmission rebuild guide.
Sometimes, it takes a simple question like this for others to even notice a discrepancy.
