Hi Barry,
If you are talking about the little Raydot racing mirrors you can get them easiest from one of the Cobra parts suppliers, like: http://www.finishlineaccessories.com/catalog/product_info.php?cPath=42&products_id=192&osCsid=79421763c0d...
Be sure to get convex glass for passenger side (maybe even driver's side). I have a pair that I haven't mounted if you want to fondle them and decide how they'd look on your car.
Cheers,
Mark
