I chose the 8.8 because at the time I wanted to upgrade the jeep, the superior s35 kit was no longer available. There is a guy near me that offers the 8.8 swap with front regear for 900. All of the brackets, welding the tubes, etc was included. In hindsight I wish I had spent the coin for new seals as they are now leaking. I have wheeled this setup for 3 years and have had no problems, other than leaks which started year 3. The fat pumpkin has annoyed me at times but for the most part is not an issue. Knowing my rear axle is somewhere between a 44 and a 60 for strength has given me a lot of peace of mind. Parts are cheap and plentiful and you don't need 'special' axle shafts for increased strength. One downside that carries over from a Dana 35 is the c-clips. In the event of an axle break, c clips make it more difficult. Overall I am very happy with the swap.
