Hey Zach... thought I'd stop back in and show an update of where I currently stand in my use and work with your great start on this truck..
Engine is from the old 3D Creations site. and the body of course started from your download above. Chopped the top, and started working in fenders and running boards. The finished product will be a full custom street rod, with a full-tilt front-end, suicide doors, solid bed cover, wooden bed floor, and a full interior.
Thanks for sharing the start of the body with those of us that like to tinker and learn!
