davidn, nice truck project going there. Oh, there is NO stupid questions. We have all had our turn asking them ourselves!! This is a great site and lots of knowledgeable folks around here. As one bolter puts it "knowledge is the best resource" and there is plenty of it her. Good luck on the project. It looks like you got a nice dry place to work on it.
Oh, before the moderators get you try to put your photo's in something like photobucket or webshots or something like that and just post links.....something about it uses up lots of band width?!
Keep us posted. Lots of AD trucks around and you can get most parts from some reputable sources. Just ask the questions!!
