If you are like me, ya just like old trucks but don't earn your living fixing em. I had to buy a book..or two. I bought "How to restore your Chevy Pickup". It is pretty basic, but does help you develop a plan. The Filling Station even sells it in their parts catalog.
If you don't know these sites, check the links on this page and/or look at Fillingstation.com, Oldchevytrucks.com, and I am sure others will add a bunch of websites of good places to buy parts for your 65...
