40 ford door glass teak help needed

I need some help with the (front door) glass rear channel. This is the channel on the back side (toward the rear of the car) that the door glass slides up and down in. Mine are missing on my 40 deluxe Tudor sedan. I have a 39 standard parts car with them in the doors but I wanted to know if they are the same before I unrivet them from the door. Does anyone have good clear pictures of the glass channels in the rear side of the front door of a 40?

Or does anyone know if they are the same or differant on a 39 and 40?

Thanks fellow hambers!

 

Even if they're different you should be able to make them work with a bit of tweaking. I make mine frome scratch.
And I'm not to bright.
