hello.
i have a 57 1/2 ton, and i removed 4 of the original 7 in the rear, leaving me with 3.
in the front i have a 350/350 also, but went with a 3 inch dropped front axle, but also removed 1 leaf, the shortest, and that got me another 5/8" drop. so maybe you could take 2 leafs out of the front and see how it does. not sure if i would remove more than that.
it softened the ride up considerably.
hope this helps.
