I put one on my 14 vert. it's tight but not hard at all. No need to remove brace. be sure & locate the two holes the groments go in so you can see how far to the right it goes. If you have an auto, the cover will have to be notched for a hose on the driver side front. Cover cuts easily with a box cutter, just cut it as small as it takes.
As for cleaning, as you said, plastic would have been easier. Rubber doesn't wipe clean very easy.
Looks good though, I'll try to bet a photo tomorrow.
Be aware the kit also comes with a plastic extension for the oil filler cap. It SNAPS in place and does not want to come out.
