I am gathering parts to swap out my 6l80e to a 4l80e in my awd 08 escalade. Tranny is almost done from Jakes. Got the harness from pcm of nc. Any info on front and rear driveshaft lengths or factory replacements? Or anything else I might need. I am not 100% sure if the transfer case would bolt up. I would like to have all the parts ready to do the swap in a weekend. Thanks for all the help.

 

ever get this completed? what did you find out on the driveshaft
