Do you have a local want ads kind of thing or you can use Craigslist. I bought 27 AD/GMC's in the last 2-1/2 years both big and little. I bought some nice cabs for $100 and complete trucks from $200-700 Big cabs fit just as good as the little ones.

You can see some in my pictures buy somebody's project or parts truck and you will save in the long run. Especially if they have already done some of the work. Keep what you need and sell or trade the rest. Also don't know if you ever wanted a five-window if you do here is the opportunity.
