NDNCHF, in response to your original question, You can use a 47-53 mirror, and mounting bracket. However, I don't think you'd like it.
They attached to the center post of the windshield and thus, wouldn't be much use, when you have the windshield cranked-out.
I have a mirror that was supposedly out of a 40 GMC/Chevy truck that I picked up on E-Bay. If you would like a picture, let me know, send me an e-mail, and I'll forward you one.
It has a slight curve on the mounting base that wont conform to my 46, but might work on your application.
GMONIZ, I believe you are correct. We did determine Steppenwood's mirror came out of a 40's Ford Car.
I've seen several on E-Bay, since my original post, but being the "Thrifty" type that I am, haven't found one yet that I wanted to pay for. So, for now, my search for the mirror I want continues.
