Window gasket for 2006 Ford E350 - help and advice appreciated

[fr8train-SKO]

Hi, I'm working on a Ford Econoline 350 and I'm in a pickle! My bus is missing a rear window, back right (20 and 3/4" H x 21 and 1/32" W and 7/32 thickness). I'd really like to get this window back in.

I bought a replacement piece of glass through Midwest bus parts. It's the right size and tint. But I have had no luck securing a gasket and without it none of our local auto glass places will install the glass. The gasket part number for the window is 15026373. I couldn't find a used or new one, so I bought a universal gasket which had similar dimensions, but it won't work and it looks like I need the correct Thomas piece. I have had no luck dealing with Thomas either - they've referred us to Safelite glass and Safelite say that they can't help.

Has anyone encountered similar problems? Would appreciate advice on how to secure a gasket or otherwise get this window in. We are in North Carolina. Many thanks!

Have you tried a Thomas dealership?

what kind of window is it? the universal gaskets come in different sizes, but like the last post says, thomas dealer might be it if you truly need an OEM gasket

It's the rear right window, on a minotaur model Thomas. We've tried both Thomas dealers and the factory.
