If you follow one of the links to an earlier thread, you'll see that there is Ruf part that is added to the underside of the cap. Bill V has an authentic Ruf rubber "lip" on his car. In one of the pictures I posted, you can clearly see the rubber lip.

Anyone know why Ruf put the oil filler on the right rear quarter?

I'm not planning on going far beyond the front and rear bumpers with the conversion yet, but the rain gutter note above is good for the thread.

The second post (history) was pasted from a site that had the specs for the YB, but you'll see the guy mentions his puzzlement over the top speed advantage of the YB over the 959. Removal of the rain gutters and the small mirrors (did they run with them?) gave the YB it's top speed advantage for the test. I remember reading the article back them and was amazed that such a small change could reduce the car's drag so much...then I went to engineering school and learned about frontal area and aerodynamic drag.
