I removed 3 leaves on my '51 3/4 ton pickup. It sits about 1.75" lower and definitely rides smoother, and there is still plenty of space before the bump stops. If I remember right, there are 7 or 8 leaves on the 3/4 tons. The shortest ones don't really do anything unless you get alot of weight on the truck. I removed 2 of the short ones and the 2nd to longest and I'm happy with it. Like others have said, it does lower the load capacity of the truck. And yes, you will need shorter bolts if you take out 3 leaves.
