I'm planning on putting Weld S71 wheels on the rear to match the fronts. The offsets will be different so the axle lengths need to be changed. The gear ratio in the Dana is a 4.56 but I only need 4.10 for the way I'm using the car and I'm thinking of changing brakes as well as the differential. Rather than pull everything off the Dana 60 and try to sell a bunch of used parts I think it will be easier to just build a new rearend that drops into the car and then sell the S60 as a complete unit to someone who is building a drag race A body. I could also have a new S60 built with all the parts I want but I think the Ford housing will give me a little more room under the car. It looks like the Ford costs a little more money than the S60 but not a huge premium if I stay with bracket racer parts rather than pro parts.
