On my '46 half ton, I figured out that the front springs were the same eye to eye length as the back ones but not arched near as much. Since I used a clip in the front, I put the front springs in the back along with 2" lowering blocks for a total of 6" of drop. 275/60-15's tuck right in under the fenders. I don't know if this works on an AD, but it's worth a look and it's really cheap. Have fun.
