Finding used differentials with the higher gears for a gear swap is pretty difficult and/or expensive nowadays. You can buy aftermarket parts and have a gear change done, but you will probably have more into the gear change than you paid for the truck. Even with the higher gears, the truck is not suitable for highway driving.
Vintage Power Wagon .com is having ring and pinion gears made with the higher gearing and should be selling them soon. Get your checkbook out.
