1979 ford f100 floor covering

My wife’s1979 Ford f100 floor covering is falling apart. Any suggestions?

Have you tried jcwhitney,com and searched for floor covering? I bought a full floor carpet for an older model pickup a couple of years ago for about $120. There was a rubber underlayment attached to the bottom of the carpet.

for old Ford restoration parts.

Or use the old one as a pattern to cut anything !
How about some nice olive green shag carpet ?
