The 3/4 ton springs are identical in length to the 1/2 ton springs, but may/may not have more leafs. In fact, the whole 3/4 ton front axle is the same as the 1/2 ton, except the spindles and the 8 lugs. My gut feeling is the 1 ton is no different.
If you lived nearby, you could come by my house and pick up a 3/4 ton front end for free...
