I have a 32 Tudor sedan
To lower it, I reversed the main leaf, then removed (starting from the bottom), the 3rd leaf, then skipped one , then removed the next.
I then made a spacer to take up the gap so the U bolts would work accordingly.
This lowered the car a bit more than 3"
In your case, just reverse the main leaf, and remove one leaf should do it for about a 2" drop. After you reverse the main leaf, you will have to cut back the ends of the first leaf so that it doesn't bind into the reversed spring eyes.
Make sense?
