I am wanting to install a total of 5 lid shocks on my 08 Cougar Advantage (three for the tackle storage compartments & 2 for the back fuel compartments). Currently they are not installed, so when I open my boxes all the way, all of the pressure is placed on the hinge in the fiberglass. What size shocks do I need to install? On the BCB store they offer a long and a short. The Long is 15inches extended and compressed at 9.5, the short is 10inches compressed at 7 inches. Also, what poundage would you guys reccomend, they offer a 30, 40 & 70#. Thanks for the imput.Matt
