Front tires bow outward slightly

I have a 72 dodge dart and I noticed when I first got the car the problem didnt exist. both the drivers side and passenger side front tires bow out slightly creating excessive wear on the inside of the tread of both tires. I know the entire front end probably needs to be rebuilt, but what causes this so I can just fix the problem for now since its my daily driver. is there something I can adjust? I also noticed that the passenger front tire bottoms out easily and isnt as firm of a ride as the drivers side, it has an extra flop I guess you can say lol Torsion bars are worn out?

thanks
