Here's a thought, I have a Yana Shitty seat cowl sitting right here in red. It's sitting here because nobody is going to buy it because it is what it is. Nothing wrong with it really, it's better than nothing, but the fitment is a bit wonky due to the fact that is a Yana Shitty. Anyway, it has hardware, and assuming the holes to bolt to the actual plastic cowl are in the same place, and they should be, you can have it for almost nothing.
Just strip the hardware off the Yana Shitty and put it on your factory one. Maybe not the best, but it's an idea. It did lock and unlock just fine, so the hardware is decent enough.
