I like the idea of buying the 12 bolt and using it as it is until the posi goes, probably not for a while. When it does, then spend the money on the tru trac.

4.56s with those 28" tall tires would put you at ~2,050 rpm @ 75mph in 6th gear. In comparison, 4.30s would be 1,935 rpm and 4.10s would be 1,845 rpm.
