The best piece of advice that I recieved when I started my truck was to sit down and write down all the things that you need to do and then divide them into workable groups. This way you can get a sense of accomplishment throughout the process. Start going to local car shows, introduce yourself to as many people who are knowledgeable or have the type of truck you like.
My experience is that as soon as you can get it ready for body work the better, as that is what has taken the longest and has cost the most money.... Good Luck, don't lose the faith.
