I know someone in Las Vegas with a 68 f100. It has a bad rod knock. Its a 360 with a 3 speed long bed. Its a rough truck, but its basically rust free. The cab has good sheet metal, the hood is straight. The rest of the truck is a bit rough. If someone is interested shoot me a PM and ill help you contact the owner.
I figure a truck enthusiast somwhere can do something with it or use some of the parts. The owner does have a clean title.
