I'm looking for these swivel corner keys and also a couple on the latches. As you can see from the photo that the key on upper right is missing the downward part of it, the left one is ok. The lower right latch has the same problem, it's there it's just broken off. The other issue in findings these is that each corner uses a set screw to hold the left and right side frame together. Any help would be much appreciated.
Thanks
Bill
