Need 65 Barracuda info ** Updated **

Hi everyone. I'm going to look at a 65 Barracuda in a few days, and I was hoping that a few early A-body experts can help me out. The car is supposed to be pretty original with 38k miles. I saw some pictures of the car and engine, and it looks pretty good. They used it last year to go to car cruises, so it has been driven recently. The guy told me they have replaced the floors, and went through the entire brake system from front to back.

Here are the issues I'd like to address:

1. It has a 273 and automatic, and the owner says it's a Formula S, but it has a 2-barrel, and the Formula S came with a 4-barrel. I know that the carb could have been replaced because a lot of people did that in the 70's when the gas prices went through the roof, so how can I tell if it really is a Formula S or not?

2. What structural problems should I look for? Are there any places on the frame that are problem areas that I should specifically look for?

3. Are there any pieces that are super rare, or almost impossible to find? The car is supposed to be complete, but sometimes people will keep or sell off a super rare piece before selling the whole car. Also, I plan on doing whatever restoration is required, and I dont want to find out that one piece is made out of Unobtainium and costs more than the whole car, if I manage to find one.

4. Is there anything else I should look out for?

Thanks in advance for any help that anyone can offer. By the way, he is asking $5k for the car, so feel free to comment on that as well.
