1973 Duster Need Lots Of Help

There is no need for a cage or a roll bar unless you have crazy HP...Kid, manage your money wisely and invest in the right things and that car will take shape very soon. Prioritize what is important such as suspension, steering, brakes, etc..the things that if not done correctly could hurt you or someone else...My first Dart Sport had a 360 without a rollbar and was VERY safe :D You have the right idea just keep pressing forward and i bet in a short time you will have everything you need
