your current front axle is maxxed out with 35" tires... plan on breaking it, within 3 months. your rear axle might last a year... MIGHT.

you'll need one ton axles.
if you're set on 14bolts, then you should know there is no point in using a 9.5" semi-float 14bolt. use the 10.5" full float. BUT, for all intents and pursposes, the 10.5" 14bolt has HORRIBLE ground clearance.

you have lots of options for the rear axle, so don't limit yourself to what most people use. the Eaton full float rear axle is as strong as the 14bFF, and this is definately the board to find one!

your front axle options are more limited, and dictated by your T-case. my suggestion would be to swap your 208 for a late np205 with the 6 bolt round mounting pattern.. but get one from a ford or a new GM and get driver side drop. then get a 78-79 ford one ton front axle (driver side pinion)
your rear axle choice is wide open, and i'd just go big, so you can feel safe. get a huge dana 80 or something.

good luck with your truck
