I had the same scenario with our 68 and went with a early 12 bolt truck rear end, Yukon 5 lug axles, Eaton posi w/ 3.42 gears and new ring & pinion.
I wanted a lower highway rpm and a low 1st gear so went w/the 700r4 transmission to achieve both. At the end of the day it really depends on what your goals are and that'll decide how you get there.
