Not sure the proper terminology, but I'm talking about this piece:

My new to me 2003, the flap is completely rusted in the 90 degree position.  And every mounting tab is broken.  I went to the junk yard today, and looked at three AVY's (2 2004, 1 2003), and every one had tabs broken, or the hinges seized like mine.  I took one that only had two tabs broken and its hinges were somewhat movable.  Hoping some epoxy to fix the tabs and penetrating oil on the hinges will help, but beyond buying a new one ($200!!), is there some tricks/fixes to make this piece more workable?  The small piano hinges on something exposed to weather where moisture collects under the mat seems like a very bad idea.

EDIT:  I should have searched first, but didn't know the terminology...."Midgate Flap" seems to be the ticket.  Looks like most are using fiberglass or JBweld to fix the tabs.  Guess I'll try the same.  Wish someone had made a replacement of a better design.

However, could someone simply explain the purpose of the rubber pieces and tape?  I though that was something the previous owner had added to keep the flap up, but it appears it's a factory item.  Is the tape supposed to hold the flap to the backside of the midgate, and it all move as one assenbly?
 
The flap should have adhesive backed foam strips covered with a friction reducing "tape" on top that allow it to slide as the midgate is dropped down and to provide a bit of protection. Anything that looks like electrical tape is simply damaged foam pads or pads that have heated up enough to cause the tape to slide out of position. If they're in bad condition, rip them all off, clean up the surface with an adhesive cleaner and using a bit of creativity, you could replace them with your own version. Could you live without them? Yes, technically.

As far as the hinge goes, it sounds like the midgates have been subjected to harsh conditions, or ironically, have rarely if ever been used. After more than a decade, my midgate looks almost new. As with anything, maintenance is key. The idea of oiling it is your best bet. Get it well lubricated and just work it back to life. It should have a strong spring that keeps it flat against the midgate as it's opened.

If you need some specific photos of any part of the midgate, let me know.
