When I bought my car it came with a gallon size ziploc bag. The PO gave this to me as "what's left of the broadcast sheet." The bag was filled almost entirely with upholstery foam, carpet bits, etc...and a some little chewed up bits of paper. Seems like a mouse used it for some insulation in his house!
I finally donned my mask and gloves to deal with the contents of the bag, which included all of the little seat parts, some petrified turds and, at the very bottom, the mummified remains of the source of my problems. It also had a lot of pieces of my broadcast sheet of various sizes and conditions, along with a few random scraps of paper (McDonald's scratch and win, gum wrappers, the usual). I found a couple larger scraps in the glovebox. Seems to be mine, I can make out a few numbers on the sheet that seem to relate including the last 2 of my VIN. Sadly, my car seems to only have one sheet in it, I looked in all the other places but I suspect it was under one of the front seats, which were recovered before I got there. At least they saved it! I've thought about trying to sort it out and put it on some kind of contact paper, but I'm really not sure it would be worthwhile.
