I know this isn't rocket science, but is there anything i need to look out for? Tips, tricks? Figure 13 shows it all i guess.......can this be done without removing the center section of the rear? http://chevy.oldcarmanualproject.com/trans/56spcra/56spcra08.html

It's been awhile since I changed one, but I;m sure that it can be changed while in the car. The only other thing that I remember is that you do not want to install the seal flush with the center housing. Seems like there should be a small gap between the housing and the metal lip around the outside edge of the seal. I think the shop manual has a specific amount, but I don't have my shop manual with me right now.
