Repro rearview mirror from Mike's is spot on.

[P.S.]

Just received the repro rearview mirror for the Tudor from Mike's A-Fordable. It is very difficult to tell it apart from the original! The repro glass is smoother (the original has the slightest hint of "waviness" to the glass), and just barely thicker than the original, but the edge and color and reflectability are exactly the same. Wow!

Nice to see reproduction parts that are actual reproductions, and not just barely "good enough". Well done, Mike!
