This 1970 Barracuda was up for bid on Ebay. It sold for $5,677.77. No driveline, no interior to include the dash. The VIN says 340 but the rear end is a 7 1/4. Not much good sheet metal, I could go on but look for yourself...
I always paint the car and then put on the Vinyl Top. I don't completely paint the top but I do taper it back at about 8in. I do this because I'm lazy and don't want to mask the whole top.
There's a guy who comes to Carlisle and has two tables full of radios. A B C E, AM, AM/FM with and without 8 tracks or cassettes. They start at about $25. The most expensive I've seen was $300. He's been there for the last 3 years.
