Need help with door frame part

[Ramblin' Rec]

Here are two pictures (up is to the left, 2nd pic taken from below the piece) showing that on the bottom of the latch side of the top door frame, the piece that the rod pocket cover attaches to has let go. Apparently the screw broke (I have no idea what the PO did with or to this thing) and somebody tried to drill it out. So it's now hanging on only by the rod pocket screw, and the rod pocket is essentially flapping in the breeze. I emailed Adam at TM, and his response is that that's a part of the frame and can't be replaced. Well. I think it has to be replaced somehow. Any ideas as to how to fix this? Epoxy? Thanks for any help!
