32 Front glass channel HELP!

[hotrodA]

On my 32 Tudor sedan, I discovered a piece missing that is critical to the front door glass install.

It is a sheet metal U-shaped channel that surrounds and supports the large front felt that the glass rides in. It is approximately 18 x 1 x 1/2", and attaches to two brackets inside the door front. It is dimensionally larger than the rear channel. I can't get the existing one out to measure accurately.

Is this reproduced, or will I have to fabricate it? Neither UP nor Drake show it.

Thanks in advance! I'm up against a wall with this aggravating glass
