Hello Trevor;
It to have a 9430 long box, 1952 version. If you want the build details you can go to the GM Heritage site and pay for a package containing info on your vehicle.

Good luck with your project and as said above there are people on here with a wealth of knowledge to help you through.

Mark
P.S. cool to have your Grandpa's truck!!
