Behind the seat I found a jug of anti-freeze, a can of brake fluid, the handle to the jack I hope i never have to use, jumper cables, an assortment of rags and gloves, the spout attachment to the gas can mounted on the bed step on the passenger's side, a spout for puncturing an oil can (when it came in cans), in the glove box I found 2 sets of points(one might go to the 283 in the truck, the other no way), a main bearing seal that can not go to this truck, and a thermostat--also a crescent wrench and an ice scraper.
Some stuff can give a clue to some of the issues your truck has and some are just puzzling.
