Hot Rods 36 ford pickup springs

I am about to begin the process of mocking up the suspension on my 36 pickup. I am running split wishbone, 4" drop axle, and stock spring in front. Rear will be a 9" with radius rods and stock spring. The truck will have a flathead with t-5 trans. I want to get it as low as i can with fenders on it. I plan on flattening the rear crossmember, but i also want to remove some leaves from front and rear springs. I am looking for sugestions on how many leaves to take out to drop it some and give me a fairly soft ride.
