i have a 1968 mustang that has alot of rust underneath the car and a bit on the headers. Is there anything that can be done without ruining the car and that is not to exspensive? also would rust have anything to do with the car leaning a bit to left?

 

do you mean rust like, holes that you can stick your hand trough, holes that you can stick a pencil through, or just surface rust? rust on the headers is gonna require you taking the headers off, sanding them, and painting them with some kind of high heat paint, not to expensive, just a little time consuming. If the rust hasnt eaten all the way through anywhere underneath then i wouldnt worry bout it
