Tonneau Center Hinge Cover

I tried finding the rubber hinge cover, but can't find the part number -- doesn't seem to be listed in the Ford Tonneau diagrams I found online. I know the covers do not make the bed waterproof, but after two days of rain I was amazed how much more water got in on drivers side were the cover was missing. Anyone have any idea of the part number or where I may be able to get one...or a way to use something else? I have a 2007 ST.

Thanks!

Picture to illustrate what I am looking for:

Good luck. You and about 1000 other people are looking also. If you read through the different questions about this same topic, there are a lot of good ideas out there.

Tried Flex Tape and some pieces of rubber. Not my finest work, but let's see...

Great idea. Looks good.

Update. We had a lot of rain and it worked! I didn't have water pouring into the bed. The Flex tape didn't hold on the outside, but cosmetic right now and I'll address it in the spring. I may also try heat shrink tubing.

I have a good condition Gen 1 JOB 1 gasket for sale.... Only fits the JOB 1 cover... its grey underneath, not black.
