Don't cry boys & girls, I saw many of these years cars in yards scouring for a front clip for my 77 PK41 for less than a grand. Ended up with a mish-mash of singles, bumper, header, & 2 fenders, was able to bang the hood back into respectability. One of my main early year yards (70's) that I would go to but had better luck/prices at the 2 other sister yards, later on I came back to it in the mid 80's and they had probably one of the very first grinders in the nation.
When I was all paid up with what I had pulled with the counter person (that was still there from back in the 70's) I ask him about the behemoth out in the yard to which he gave me a personal tour and explained how the machine separated out the Ferrous and Non-Ferrous Metal and how the 'Fluff' was separated. I kind of thought, oh no I better get back here and grab a bunch of prized stuff I don't really need but would like as the very busy yard was packed and the Environmental people were all up in arms about landfills & junkyards polluting the water table in that state, yada yada yada... The person showing me the grinder pretty much said everything that wasn't a year or two old would be ground up as body shops weren't calling on those cars anymore.
I just checked Google Earth and amazing the yard is still there and their website says 7 decades of business, but the yard looks nothing like it did back in the day, more like a super hygienic CoParts, with all the dirt paved over and many references to "Transfer Station, Auto Recycler, United Recyclers Group. Nothing but Imports there now.
Even back in the 80's this was standard cancer on the late 70's C-Bodies.
My 1976 Gran Fury Brougham had fenders & quarters that looked like this but luckily the floors and uni-body frame were solid but in it's end days of the late 80's (10+ years old) it went to the scrap yard as you couldn't sell a car back then with that much visible rot.
Oh well...
