Missing pieces for Covermaster "The Edge" tonneau

Recently purchased a used 5ft fiberglass tonneau for my 2001 DC. The hardware is missing from the lockset to the latches. Web search revealed that Covermaster is out of business. If anyone has one and could take a picture of the inside pieces or could describe the mechanism it would really help me out as far as getting replacement parts.

 

So all you have is the "lid" piece and no hinges or brackets of any kind?

 

I have the fiberglass lid with the frame and hinge attached. What I don't have is a way to secure it in the down position other than its own weight. I don't know if there's supposed to be cables or rods that go from the outside keyed handle to the latches. The D hooks are attached to the frame but the latches are shot. The keyed handle is broke off inside but I think I found a similar replacement for that online.

 

some have the latches built in to go under the rail


others like the Undercover I have use rail mounted brackets that the lock latches to (notice the tab in the bed near the back)

 

Thanks for your response. My cover goes over the top edge of the tailgate so you would not be able to open the tailgate unless the top is lifted. When I get home I will take some pics of what I have which should help.
