A dana 35 is pretty light duty. A dana 44 or dana 60 would be stronger. The gears are a bit high for an overdrive as 3.08 gears are already almost considered an overdrive.
I think you would be happier with a stronger rear. The one mentioned would probably live pretty well behind a 235, but the gears aren't that desireable with an overdrive... unless the OD ratio is about a 0.85:1. For all practical purposes 3.55 to 4.11 gears would perform the best. the 3.55 being on the economy side, and the 4.11 being better towing or hill climbing gears. A 4.11 ratio is effectively a 3.0 ratio with a standard .73 overdrive.
