new info:

i still have not actually seen the truck, in person, because the guy is slow to email me back, but i did notice in the picture that the bed doesnt match the truck. the bed is from a 73-75 model as it has trim all the way across the bottom. i think the bed was the same from 73-79, just different trim options from year to year. here is a link:
