Hell yeah, my kinda car! B-Bodies and E-bodies are where I started! I help build a 72 Road Runner w/ 400 BB. Nice car, decently fast car, always street raced with it. I also remember helping my buddy put together a 73 Charger to sell, it was only a 318 car though.
All I can say, Year One and Paddock will be you're friends when restoring. First thing is first. Pull out all the interior, check the floor boards, trunk floor, quarter panels, trunk extentions for rust. Judging by the pics, you have a little already in the quarters, hopefully its nothing major. Luckily that car DOESN'T have a vinyl top, those can get real nasty underneith. Helped my buddy once pull off one off a 71 Charger... lets just say it looked like swiss cheeze! Trust me, it was bad, The roof was literally sooo weak without that top being there, it eventully caved in. It was a lost cause anyway and only used for parts. A complete rust bucket.....
