I recently inherited a 2005 hummer H2. It is in prime condition except, after my uncle passed, some one who knew him tried to break into the bed and busted up the tonneau cover. I was wondering if anyone on here has just the cover flap (installation rails are all still in good condition), or the actual lock mechanism if I am able to bend the cover back into shape? I can include pictures of what is busted if you may have a part that I need. Thanks for your response!

 

From what I've been able to determine - GM contracted Fold-A-Cover to make the covers for them. I've never seen them advertise anything really for the H2 but they might have certain parts.
