[Rovernet] P6B final gearing

[Gianni D'Ortenzio]

I have been thinking of doing the swap putting the 3500 diff in the 2000 TC. Many people have told me this is a good thing and certainly the TC seems to rev hard and high at highway speeds. One of the diff seals leaks anyway. Are the seals in the 3500 any better given it is a later diff? Two benefits would seem to make it even more worthwhile. 
Cheers Gianni
