I bought a set made especially for Winnies from this website:
https://dragonfly2.net/.
They come in colors, I stuck with black, They fit my rig, don't know about your Winnie. They fit every corner. I broke the drivers front trying to force it into position, but notified him and he is sending me a new one at no charge. He made them from a 3D photo.
My tube of Dicor was old and had turned gummy and was hard to work with, so my first one looks crappy, I used pure clear silicone on the rest of them and they look great.
