Best route to take

[lilbuster20]

Hey my truckin buddies! I am going to start overhaulin my shortbed truck in the next month or so. I was wondering, how should I start or better yet, what should I do first. My shortbed has no motor or trans. I already switched the radiator core from 2 headlights to the 4. You guys have some awesome trucks! And I'm sure you didnt do all the work at the same time. Should I rebuild my engine and tranny first or focus on the body itself. Any help or direction will be gladly appreciated!!!!
