Customs 1940 merc... keyway

Does anybody have the dimensions of the steering column keyway for a 1940 Mercury I'm not sure if they're the same as 1940 Ford but I need one so I need the dimensions such as with Etc

 

They should be the same. I'm not certain what you are looking for

 

Here is a pic

 

I think he wants a Woodruff key.

 

Is that what its called...that's what I need,the dimensions a the woodruff key for a 1940 merc..

 

Ace hardware has them--I just get a few that are close then file to fit. Have done several 40 Fords this way

 

As I suspected. A keyway is the groove that a key fits into

 

Thanx hamb bros.
