I went to my favorite salvage yard not far away,the one that still keeps "some" old vehicles...there was only 5 square bodies there,same ones I saw last time months ago,only with many more parts missing..
A few years ago they had over 100 of them..finding used parts any good here in a salvage yard, is futile lately..any they do get in get cannibalized and crushed in a matter of a week or less..
I did see a "Harley Davidson" custom edition Chevy van of 1990's vintage with a 6.2 diesel in it that was pretty much parted out other than the engine & transmission..probably one of two built or something !--I always see something unusual in salvage yards--and always come home depressed,after seeing some vehicles people junked that are way better than what I'm driving,due to "no title" or they simply decided it was not worth putting a transmission in,etc..
A lot of the yards here are just piling engines and transmissions,steering boxes and racks,and drive shafts from fwd vehicles up like cordwood,and not selling them to customers..
I guess a lot of them feel its better off selling "cores" than having to stand behind a part they sold that may have been why the vehicle got junked to begin with..this certainly isn't helping those of us into older vehicles--"cash for clunkers" wiped out 90% of all the old trucks some long time junkyards had hoarded..
