Not sure where to post this so I will start here. I have a unicell box on my fuso. The rear of the vehicle has a large storage compartment. There is a handle in the middle that unmatched both sides. The problem is that it only unlatches one side. Not sure how to tackle this. I tried unscrewing the latch but it did no good. Possibly I need to take the lock out? Idk, but before I screw something up I thought I would ask here. Thanks for your thoughts.
