Classic pick-up truck search

I thought I would ping this group for background info. I have the hots for a mid 50's to early 80's stepside pickup truck. Probably prefer Chevy/GMC (based on styling) but I am open to anything. Original, numbers matching, etc. does not matter to me. If an older truck, a replaced front clip or suspension, disc brakes, etc. does. Following the collector car maxim, I'd rather by something more or less completed (restored, modded, etc.) than a "project". Chopped, channeled, narrowed, shaved, frenched, etc. all OK. Has to be able to be driven (not a pristine show truck) and used as a pick-up (rarely) and weather tight (may have to sit outside, again rarely). I would appreciate any/all general opinion, where to search, resources, etc.
