Best way to determine full bump shock length (fully collapsed) on a coil spring application is to remove the coils and set it on the bump stop with the full weight of truck. Measure mounting points and get a shock that meets the minimum requirements and has the longest length. For a leaf suspension break down to main leaf and cycle suspension. There are pics and details on the leaf setup in my build thread. Obviously, the new shock mounts and panhard shoud be in place when the process is done.
