You all are a tremendous resource. Thank you for your time and knowledge. Looks good for a pretty version of the farm truck we want, but I'm looking to give less than asking on this one. All that said, I'm pretty interested in the odd features this has that I like - underbody fuel tank, floor shift, full windows (my preference is to hang my arm out easily). Originality aside, those all seem like plusses. It is a bummer that it is in fact a Chevy motor and possibly frame (I dig the uniqueness of the GMC models of this era), and I have no idea what the "remote" rad cap neck is all about. Don't want to offend the owner, but I think I'll offer $12k here and see what happens.
