Radon, if your are not willing, that's fine. I however dont own an NV, but am looking to the knowledgeable members of this forum to assist me with a project that involves this vehicle. You're suggestion is not helpful and assumes too much. Maybe there is someone that works in a Nissan service department or weekend shade tree mechanic that would be more willing to assist.
I am wondering if anyone can provide a measurement of length (bolt hole center ti center) and deflection (from center of spring to line drawn perpendicular to a line between the mounts) of an NV3500 rear spring both loaded (normal vehicle weight) and unloaded (uninstalled). Thinking of using it in another application, but need the measurements first.
