I am also in the market for a long bed tonneau
I remember a past thread on a member who bought a used Ford tonneau cover that fit his C10 pretty well.
It was an Extang Trifecta 2.0 tonneau cover for a 1978 Ford 8ft. Long Bed.
Extang only offered a tonneau for 1975 C10’s and up if I remember correctly.
I did save the photos though.
I like the way it cover the rails, tailgate and the bed pockets.
The Extang web site still offers this Ford model version but nothing for the C10’s.
I am still thinking of the color matched Gaylords hard cover but…$$$$$$
