Truck help question

[SideShow Bob]

Fords are Fords who cares, the drawing/part should be similar. Still 1978 is stretching it for parts unless there is a rural dealer out in the flatlands that has one under several inches of dust in the back room. And that age for a plastic part from a junk yard would be so brittle it would break trying to remove it.

Edit: try reading the original post again, Sparky says "1976" not 1978.........
