'68 Barracuda Notch

I won't be able to get the car into my garage until this weekend, but I took a flashlight out with me last night and did a little more investigating. The trunk pan looks to have been removed at some point (possibly for a fuel cell), but it has been replaced. There are still some holes, but nothing major. Both floor pans have small patches in them, but it doesn't appear that they were done correctly. I'll know more when I can pull the carpet. I mentioned that the very bottom of the rockers had a little bit of rot and I found one small hole at the front driver door jamb, but the rest looks pretty solid.

I was a little worried about interior wiring after seeing what was in the engine bay, but under the dash doesn't look too bad. There is a bundle of wires for the aftermarket radio and a couple wires here and there for the additional gauges, but no jumbled mess of factory wiring.

The first project is addressing the inconsistent brakes because its a safety concern for me. Any ideas on identifying front discs?

On my truck, I know the year of everything that's in it, so when I go to the parts store, I know exactly what to ask for. I need to figure out exactly what I have so I don't run into problems in the future.
