I'm missing the same one. the engine cover is starting to wear away the aluminium pipe underneath. I think I'm going to have to resort to Alfa to get this one.I'm missing the front left, the odd one of the four. The engine has a metal ring for the plastic plug on the engine cover. What does that rubber bung look like ?
My front left plastic prong (1/4 section broken)...I can take a photo of the rubber ring in the front left bracket if someone can show me a pic of what is supposed to clip into it, mine seems to have broken off the engine cover.
