The plain black filler panel for a TA, and a set of smoothed valve covers (or who can do them). Thanks!

 

Check through some of the sponsers. Some of them have what you're lookin for in the smooth valve covers. As for the black filler panel, try Afterthoughts Auto.

 

You can polish your own filler panel. (Or send it to me, I'll do it cheap.)
