Leaf help early A body

I bougt the XHD springs for the Demon and the back end of the car was high in the air, I originally thought it would come down but after a year, it was still high. So I flipped the front hanger to bring it down. Now it sits just nice. For my 65 Cuda I have just regular HD springs. The car isn't finished so I can't tell you how it sits yet.
I ran the super stock spring on my old 66 Valiant, and I didn't like them on the street because the car sits crooked, because one spring is built heavier than the other, but they did work good.
