yeah, I have looked at that pdf,lots of shocks...lots of shocks....I cuoldn't really find one that had the same mounting ,, right length as well as the same amount of freedom...but i guess as the shock gets shorter you will have a bit less available up and down movement. Seems as though some of the short shocks only have 4 or 5 inches of travel which seems a bit short for a truck that will be used as a truck on occasion. Maybe I should stick with a long shock and move the mount up and forward hair. Not much room to move up, but could manage i think
