Is my rusty 68 Barracuda salvageable?

Any tips on finding shells? Originally I thought the second gen Barracudas were meh looks wise (my dream always being a 70-74) but it's grown on me and the side profile is really attractive. I'd like to be able to find a good shell to transfer everything over to, but my craigslist findings have been scarce Barracuda wise.
The 67-69 Shells are out there, but going up in value like everything else. 70-74 forget about, til you start making big money. Just keep looking for a shell they show up just have money ready.
