i have a 96 dodge 2500 with a dana 60 front and dana 80 rear both with 3.55s and the 80 is a limited slip. i would like to trade for 4.10s and i heard to go from 3.55s to 4.10s in an 80 you also need to change the carrier so if someone could verify that for me that would be great.. send me an email or post and let me know if your interested... shawnsack@yahoo.com
