Trunk cardboard 69 Cat

Finally found repro trunk cardboards for my 69 Wildcat convertable, but I can't for the life of me figure out how they install. Or even which is right or left. Can someone post a picture? or at least let me know if the one with the rectangular hole is right or left?
All input appreciated.

Where did you find repros?? o No: Inquiring Wildcat owners would like to know!! :Comp:

 

Not sure for other years, but they had mine. Go to their ebay store link.
