Car is a 69 Coronet R/T convert. The car has Dynamat and Dynapad installed throughout the car. The trunk has been completely boxed in with carpet and extra insulation for sound deadening. Even with heavy duty NEW rear leaf springs, the car sags. The springs are almost flat. I am sure that it is from the extra weight (estimate 500-600 pounds). What would you suggest to improve ride height and handling.

To correct ride height, get the springs rearched or buy new ones.
To improve handling, you need a stiffer spring. Again new ones, with a higher spring rate. Or add a leaf to your old stack.

As mentioned, the springs on the car are brand new HD from Mopar. not sure that rearching will help and i don't know who would have some "super HD" springs. Any and all help will be appreciated

I have done alot of customers cars with new mopar springs. They do seem to be lower than maybe some of the originals. Since the customers usually had larger tires than stock on the back they need more clearance so i just had them rearched 2 inches and they work perfect.

You asked 2 questions. Ride height and handling. Rearching them WILL give you more ride height without changing the srping rate. Is that what you want? Since you mentioned you've added 500 lbs (which sounds like alot BTW). Adding a leaf will increase the spring rate. This will improve your handling and that is a common practice when carring more load.
Rearch = ride height. Add spring = add spring rate.
Flipping the front hanger is about 1/2" higher.
