DPI carries this in stainless, painted black. Don't see it on the site (there's quite a few parts in his shop that aren't on his site, I'm assuming this is one of them). Here's a quick install guide to give you an idea of how it works:
1 ) Remove the engine cover by taking the nuts/washers off the hinges
and support. Start with the support, then move to the hinges
2 ) Once removed, lay up-side down on a non-abrasive surface
3 ) Dremel down the notch right in between both hinges so it is flush with the rest of the engine cover. If you're not sure which one it is, eyeball the next step and you'll see it
4 ) Test-fit the stiffiner to ensure a snug fit. If it doesn't sit flush, file and/or dremel down any high spots.
5 ) Remove the stiffiner. Probably easiest to just turn the engine cover right-side-up at this point and use your hand to break its fall
6 ) Place some glue (forget which kind, fits in a caulking gun if I recall correctly) where the stiffiner will go
7 ) Press into place, and
clamp down for however long the directions on the glue says (I think it was 12-24 hours).
8 ) Wipe off excess glue with e.g. shop towels or paper towels
9 ) After glue dries, remove clamps and re-install engine cover.
I managed to forget step 1, and had some nasty bowing on my engine cover in the process. Them suckers be
stiff!
If you're interested in the part, send an email to DPI Josh (his email is
here) and ask if he can add it to his site, as well as what kind of glue you're supposed to use.
