I know they make this type of webbing for the trunk of some cars to hold crap from rolling around m dads riviera had some, but any type would probably do. I want to put some across the back of the flap that goes in the trunk, the flap I'm refering to is the one that hides the trunk that comes out. I have some small boxes with tools and such that I would like to keep hanging from it, since I need the trunk space for the t tops

 

could probably get some at a local hardware store or a crafts outlet.
