Nice pics.
Kalaehina, putting add-a-leaves in is'nt too hard. I've done couple of my trucks, although the Dodge was the hardest since the springs were more stiff. After I unbolt one side of the axle from the spring pack, I use big C-clamps to hold the leaves together, then unbolt or cut the locating pin that centers the leaves. Then let the pressure off. Slip in add-a-leaf and reverse process. You need to put the new locating pin in before compressing the pack back together so things will line up. Use the pin to help tighten the pack. Once things are pretty close (usually I can't compress the pack together completely) put the axle back up against the spring pack and get the weight of the truck on it to help compress things better and tighten the pin more. Now do the other side. It's pretty simple if you have the right tools. Just be careful. HTH.
