9" Or 10" ?

How do you tell the difference between bare spindles if they are 10" or 9" drum brake spindles? I have a pair of '73 up drum spindles, just not sure of drum size.

Post a picture. 9 inchers have a little dogleg where they attach to the top ball joint and the 10 inchers are more or less straight. Could tell you for sure if I could eyeball them.

I might be wrong but I was thinking all were either disc or 10 inch drums, along with all right hand threads from 73 up.
