. . . you have to admit this is not one of GM's proudest designs! Kinda like the gas tanks on the 1970's C/K trucks.

x2. One of my first jobs was delivering auto parts in a 1972 C10. I used to wonder what all that sloshing noise was inside the cab. About 2 months into the job I was looking for something I dropped behind the seat. Took a peek and couldn't help but notice that gas tank. Even as a naive teenager, back before auto safety was a big deal, my first thought was WTF?!
