From the info I've seen online the "P" could mean "Sport Coupe" and or "Z28". (See Below). Although there should be a "Z28" on the trim tag. The 1981 didn't come with rear discs, lots of kits to convert though. As for rust, all of the usually places apply. Floors, rockers, trunk, rear wheel wells, etc. There is a lot of great aftermarket equipment available for these sencond gen Z28s.. On the color combo I think he meant orange/red stripes on a grey car. There weren't any orange/black stripes. I don't mind the combo. I had a 1979 that was silver with the orange/red stripes. I like the combo. That was a great car.
