Numbers Matching 1973 Plymouth Valiant

3 owner care me being the third owner. My uncle traded some guy on craiglist for it 3 years ago, just swapped keys and titles and took it home. I fell in love and traded him my 75 dart for it. I dunno why but i love 4 door plymouths so it was a love connection for sure. I want to do a few modifications such as disc brakes and possibly smooth out the body. i would love suggestions [cheap ones] as to what i can do to make sure the car is safe to drive and also looks good.

It's got bad drum brakes but is able to get me back and forth where i need to go. The body has a few dings and some places where it rusted. I'd love to install a/c for it and maybe get the heater working again as i have to put it on a on/off stereo switch just to use it in winter time. I need a cheap find for a tailpipe as it's rusted beyond saving. I'd love to find a cheap 4 door front bench seat since it came with a 2 door bench which means no leg room if i want to take my mom and dad or brother somewhere.

This is all within my limit of spending i believe except for the tailpipe which i'm afraid i may have to buy new. so look at the photos and tell me what you think. I'll take in depth photos soon these are just of it all cleaned up.
