Is this VIN a 68 340S?

Thanks for the replys. The car has lived in dry west Texas all it's life, but I haven't seen it yet and his sis doesn't know enough to find the fender tag. I'm planning on a trip to pick up one of his cars (73 Porsche 911S targa) in the next couple of weeks and will be able to get some pics and more info on the Barracuda. I'm pretty sure she is going to sell it, so after we dig up a little more info, I'll need help determining value.
