A brushed black anodized plate that matches the end curves of the original wood grain, bolted to the dash with black allen screws would look mean.
That's what I'd plan to do anyway.
Leaving a 1/8-1/4" gap from the dash to the face plate and fitting some thin red light strips between the two all around the perimeter would look pretty sweet as well.
The same treatment would have to be applied to the center console and the overhead console as well.
Are those steel or aluminum? They look pretty cool either way. Very race inspired.
[edit] I guess they're aluminum.
