Welcome to the board.
My advice to you is this; get the truck running and make it driveable and fairly dependable. Drive the tar out of it while you formulate a plan on where you would like to go with it. This accomplishes several things; first, it give you some great lasting memories that will carry you through the hard times later on when your truck is completey torn apart and you have rust in your eyes yet one more time. Second, it will allow you to get to know your truck and work out all of the little bugs and idiosyncracies (spelling?) that tend to make our trucks special. And third, it wil allow you time to think, plan, and save some money (yea right) because these things always cost more than your thought (and take 3 times as much time)

Good luck
Bobby
