69 Barracuda 383-S
It would have to be near perfect to fetch $24,000. I know a guy that spent close to $50K on a concours restoration of a 68 Barracuda coupe and was having a hard time getting $20K offers a couple of years ago.
Selling it unassemblied and it's as described I would say $6k is optimistic. More like $3-4K.
It may be a realtively rare car but the Gen 1 & 2 Barracuda's just don't fetch the big bucks.
