One thing on my to do list, but I haven't done yet, is to try loading a piece of ortho litho film part way into the holder, then load the x-ray film on top of that, then carefully remove the ortho litho fim. I'm hoping this will protect the x-ray film from the flap, and the .004" ortho litho film shouldn't take up too much room in the holder slots, which are pretty generous. These are old wood and metal holders.
