There are several obstacles to overcome with the car to truck swap:
Different spring spacing
5 lug axle shafts that do not swap with the truck 6 lug axles
Different torque tube and driveshaft length
Possibly different U joint

By the time you get the car axle adapted, you'll have a great deal of money invested in a non-original item with virtually no source for repair parts if it gives trouble later. Do your homework before beginning that project. Where in Georgia are you? I'm in middle Tennessee near I-65 and the Ala/Tenn state line. I have a complete 1952 Powerglide rear axle assembly stashed away.
