The contents of my '65 c10 lwb stepside in April 2003:
In the glove box: I found a small can of wd-40(even had a straw still, with plenty left in it), some bulbs for the 'auto parts store trailer lights' that were on the truck when I got first acquired it, a 20 gauge shotgun shell(still live), a few of the glass bulb fuses for the original fuse block on the firewall(I should have checked in there before I bought it, maybe I would have realized it had electrical demons - ha ha ha), some doodads that go to the trailer lights hookup in the back and the bill of sale from when the guy I bought the truck from, bought it from some other guy.
I found the spring thing that locks the stock jack in under the driver side bench seat rattling around on the floor.
It had a 8 track am/fm radio in it(which worked but has since been removed) with an Elvis greatest hits in it and a marie osmond tape and some other band in the glove box.
It even came with a cute plastic sign, stuck on the dash that says: thank you for not smoking.
I left that sign on there.
The spare wheel and tire was in the bed, along with a bunch of leaves.

UPDATE 01/16/2013:
So, after reading this thread originally, I wandered over to the Stovebolt page and got this thread started:
Things you found in your Stovebolt when you bought it ?
There are 350 + plus posts in there now... some of it is very funny reading with the lists of strange things people found in their old trucks, I thought you folks might get a laugh out of some of them.
