I have the Eddie Motorsport billet cowl vents pictured above. The template they have used is nothing like the originals and the fit is crap. They list fixing brackets as part of the package but only come with fixing screws. I contacted them 3 times asking about the brackets and to see if there were any install instructions when mine arrived without brackets and no obvious fixing method. After ignoring me they finally replied and said there were no brackets and to simply just drill new holes and use the self tappers included with the cowl vents. The new cowl vents are still sitting on my work bench waiting for me to fabricate some brackets and the Eddie Motorsport website listing for this product still says they come with fixing brackets.
The MS275 door jamb louvres, on the other hand, are an excellent fit although I ordered both the cowl vents and door jamb louvres in matte black anodized, the mesh on the cowl vents arrived black whilst the mesh on the louvres was silver ::shrug::
Both items arrived hermetically sealed vacuum packed and appeared to have been made in China, although I could be wrong.
Unfortunately both of these items are not repopped, if Don has some grab them as flat cowl vents in good condition are hard to get!
