just bought ROUGH 62 valiant

I just bought a 62 valiant 2 door 170 3spd. :) Very rough but complete. When I get it home I will be needing to fix rear quarters behind back tires (rust), all 4 corners (dents), all upholstery (mice), floor (rust), etc.. I have a very tight budget but am not in a big hurry, and the car is to be a daily driver (not show quality, just decent ). I'll appreciate any hints you might give me. Eventually I want to fix this up to see what the best mpg I can get is. My brother has a MAF fuel injection system from a buick 2.8 v 6 I can get from him. I have an HEI ign system I can put in it, so I have some ideas already. Thanks all!:homework:
