Projects which mirrors will fit?

Hey guys!
I just wanted to get myself some custom style rear mirrors for my 1951 Buick Super riviera (hardtop 2 dr).
Thing is i dont know which of the tons of mirrors one can find on ebay or other sellers is going to exactly fit the socket.
I´d like to buy some bullet style mirrors but i dont want to adapt the original socket.
Anybody has knowledge of mirrors that are going to fit? (except the original ones of course)

plz help

 

Bullet style mirrors are totally wrong for that car or any other 50's car or truck. unless you are thinking of something entirely different than the Mug/Cobra mirrors that I found on Ebay.

 

My thoughts are the bullet mirrors are more of a 60's/70's style,they would look out of place on a early 50's Buick IMHO. HRP

 

But they're shaped just like the body! (this was someone's 'logic' a few years ago when I asked about the 'Sporty-car' bullet mirrors on his '46 Chevy)
