datconvertiblez

Hi, I have fitted coilovers to my convertible 350z and I am wondering how I can change the dampening on my rear coils without disassembling my suspension each time. I have seen that it is easily done for coupes (remove the sway bar cover and use extenders) but I cant find much online about convertibles. I am aiming to drill access holes within the soft top storage compartment to then pass through the extenders but I don't know where to start. Has anyone done this mod before? If so, can you help me. Thanks!
