I don't believe a D35 ring & pinion will fit in our D30 axles.
At one time it was customary to use a numerically-smaller ratio in the front axle than that in the rear. For instance, a 4.09 front axle would be matched with a 4.10 rear. The theory was that the front axle would pull just a bit more than the rear would push and increase stability. AMC used identical ratios in both axles without regard to previous thinking.
A 2.72 front and 2.76 rear would perhaps be OK with a part-time transfer case. I would think that's too much difference in our full-time cases with their viscous couplings.
