When I replaced my bodywork a few years ago (previous owner damage), I also ordered the rear cowl panel seal.
Frankly, it's such crappy piece of foam rubber, it wouldn't last long at all and disintegrate.
What I found was some 1/4" 3M interior weatherstripping tape at a hardware store.
It's made of much better foam material and is self-sticking.
You can buy a 30' roll of this stuff for around $4.
The 1/4" width is just about the width of the lip on the rear cowl, so no trimming is needed.
It's been on my bike for 3 years and still going. And it seals well.
It also keeps the panel from rattling around and provides enough resistance to keep the panel secured to the latch.
It's worked so well, I've lost the roll it came off of.
