need tips for building my first truck

[MIKE52]

Im 15 and im about to start building a 52 chevy 1/2 ton truck. This is the first time i've built a truck and i was just wondering if anyone had a few basic tips for the construction. We have all of the original parts for the truck, but im looking to modify several things like a sweet sound system, power steering, heating and cooling, automatic windows, etc. So if anyone has built a 47-54 chevy before, a few pointers would be very helpful.
