I was referring to carrier and pinion bearings in the differential. That's assuming the ring & pinion gear as well as spider gears are decent.
Parts availability:
It can cost more to rebuild a 235 I6 than a 350 V8.
Parts stores make more profit off of commonly used parts than stocking new/refurbished classic and antiques parts.
Most likely your current drivetrain is made up of classic parts and may cost more to rebuild.
Function:
The AD truck was designed for work. Stiff straight axle with leaf springs suspension for pot holes and rough roads as well as working in the field on the farm.
The torquey 6 cylinder engine was made to haul loads. You frequently changed gears back in the 50's road system.
You have "armstong" steering so the original skinny tires do better that today's wide tires.
You have to decide what type of truck you want.
1.) Original
2.) Cruiser (creature comforts)
3.) Hotrod (chrome, more speed, harsh ride)
4.) Ratrod (rust is beautiful but in your case X this one out)
5.) Straddle The Fence (mostly wreck yard or donor vehicle parts...person on a tight budget)
