Looking for 10" Perception Koho 11.5 hatch cover

Where can I find a replacement hatch cover for an older kayak? I’ve looked on TopKayaker.com and found one I think will work but it’s sold out. I have a Perception Koho 11.5 kayak and the hatch is a two latch twist lock (no bag) hatch cover. I love this kayak and it is in great condition. I just need this one part that I can’t seem to find. Any suggestions on where I might try to find this part?

Have you tried Perception. They’re still in business.
