1955 Chevy 2nd Series axle swap 4x4

[rano]

I picked up a very clean Arizona 1955 2nd series 3100 pickup. It was converted to 4 wheel drive years ago. Napco want to be. The front axle is a early 60s closed knuckle with a blown pinion. The rear axle is original. It has a divorced transfer case, 4 speed and 307. It has a 4 " lift and new 33x12.5 tires. The drum brakes do not cut it and I would like to go the discs. I am thinking of just swapping out both axles for newer ones with disc brakes, but the new axles are wider. The current axles are 65" front and 62" rear wheel mounting to wheel mounting surface. I can get a set of 3/4 ton Dana 44 front (69") and a 14-bolt that need a little work for $275. Or I can look for a set of 71-72 1/2 ton axles Dana 44 (67.5") and 12-Bolt rear. I like the current look of the truck and am afraid the axle swap will push the tires out too far and look lame. Another possible direction is to use the 3/4 ton axles and get tall narrow snow tires on steel rim and dog dish hub caps to go for the old Napco look. Anybody done this or have thoughs, all are welcome.
