I am in the same boat here in MA--when scrap hit $250 a ton some years back,all the square bodies practically became extinct here as far as parts in junkyards..and many of them were actually in nice shape,because they were totaled early in life,or scrapped when the engine went sour ,frames don't rot sitting in junkyards much ,compared to ones driven in salted roads during winters..
One yard I frequent had over 100 square bodies,most of the 4x4's ,now there is just one,when I went there last week hoping to find a good spring hanger..the truck is a bare skeleton,bed still on it (junk),and sitting in dirt with no rims,so its hard to see if the frame is any good..the hanger looked "useable",but for the amount of effort to get it off,it wasn't worth going thru that much agony for me..
Another yard I knew of but haven't been to in decades keeps all the "old stuff" but most of it has been picked clean or rotted from sitting too long--called the owner,he said he has a few 1/2 ton 4x4's,that had decent hangers,but he wanted $100 each,because to get the trucks out would require moving a lot of cars and he wasn't thrilled about removing rivets..
Now I'd be better off looking for an entire frame..(or truck,I'm not in good shape,and would be unlikely to complete a cab & nose swap).
I actually HAD one sitting in my backyard for years ,in nice shape,from a '73 K10 --but I stupidly cut it up when scrap prices went so high,figuring I'd never use it..

..I did not own my K2500 then..and back then square bodies could be had for $500-$1000 in decent shape still..
I also own a '85 K10 Suburban that came from Washington state !--it spent a year in VT and two in MA before I got it in 2009 around Thanksgiving...its undercarriage was like new,compared to any I'd seen here,and it had been oiled and undercoated..has a 6.2 and a dying 700R4 in it..body was real decent when I got it too..paid $400 for it,a friend had to get rid of it when he moved to an apartment..
But life got in the way of my plans to put it on the road and fix it up--my mom was failing when I got it,she needed 24/7 supervision,so it ended up sitting in the yard all this time--the rockers are rotted all the way from front to back now,and under the doors,and I assume the once minty floors are probably weak now,the whole truck was completely buried for over a month in a huge snow drift in 2015,and the melting snow went in the doors and soaked the carpets..
Far as I know the undercarriage is still "nice" compared to my pickup,and I might have to resort to dragging it out and fix everything thats gone to hell from sitting (brakes,exhaust,etc),and get the transmission replaced..I put a Diamond plow on it but only pushed snow once with it--never did hook up the plow lights..
The fuel tank in that thing may well be junk by now too,a 40 gallon one that holds $120 worth of diesel..it may not be worth saving now,it'll need so much work..
I'm just so discouraged now,I don't know what I'm going to do..for now I'm just praying I can cob the pickup together enough to be able to use it "around town" to get groceries and pay bills,then take it off the road when winter's over--then decide whether to fix it,or part it out..
