Hey, I remember that Cobra. Nice paint job!
Some cobras have a 1/2" spacer (or so) to raise the dash rear view mirror. depends on your seating position and preference. I'm using a MG or something like that, a little taller with a slight convex curve.
Dark Water Customs makes a mount for the top of the windshield if you want to relocate your dash mounted mirror. I've always wondered about vibration.

I've seen owners (like John Marsy's JBL) use the SPA race mirrors for center and side - Great mirrors. I switch to the GT side mirrors for track events.
