Removing a 46 year old differential carrier is not as easy as it says in the manual…after a couple of hours of battling with it I finally got the original 2.79 open diff out of the 8" housing - I have a new 3.55 Yukon Trac-Loc diff (clutch style positraction) that I will be installing tomorrow. I can’t wait to drive it with the new rear axle ratio!
