what to do with this one?

Well I found this car a 73 valiant 4 door 318 AT PS.Car was sitting up for sum time but with a little gas and a hot battery it fired right up. Transmition is shot. Has sum rust in lower quarters and trunk. I have enough spare parts to probly be able to fix quarters and trunk. Only thing. That worries me iis the front and rear windshields.If I understand right they don't reproduce the gaskets,correct me if I'm wrong.Just hate to spend a whole lot of money on a 4 door.Even though I've seen sum that are cool. might just find a duster and use the valient as part car.
