69 DODGE DART HOW TO LEVEL THE REAR END

I THINK ITS THE LEAF SPRING ON THE DRIVERS SIDE REAR I MAY LIFT THE CAR SO ITS LEVEL IN THE REAR AND WELD THE LEAF SPRINGS

Welding the leaf springs may not be a good idea, they need to move in relationship to each other as the spring compresses and relaxes....

If the mounting points on the frame are good and solid, then you may need new springs and bushings...
