Coupe Rear Window U Channel

I have a late 31 coupe with original rear window wood and frame. The glass U channel rubber has dried and cracked causing the window to rattle. I removed the frame and glass and ordered a new U channel from one of the vendors. When I received the U channel rubber I noticed it was only about .4" overall width while the original rubber is about .625 overall width. This causes about a .25 gap between the frame and the window. I have searched this forum and others for someone that may have had a similar problem but could not find anything. Has anyone experienced a similar problem. Is there more than one style rear window rubber U channel and perhaps I was sent the wrong one? Is it possible something changed with the late 31 coupes?

Any help or suggestions would be appreciated

Turns out late 31 indented firewall coupes used the same thickness wood frame as cars with the roll down rear window. My standard coupe did not have the roll down rear window. A thicker window U channel is needed to take up the gap. I looked everywhere and could not find anything that would fit. The original is stiff and cracked. I found a piece of RG8 coax fills the gap well and will reassemble using it although I would like to find a proper U Channel. Just a heads up for anyone replacing the rear window on a late coupe

So what did Steve at Bert's have to say about it?

I am sure the right size is out there as I had to search for one myself back in 1980 when I did my 1929 Standard Coupe which by the way takes the same moulding.

Like you said, the one I ordered from one of the ccompanies at the time was to small.

Try searching on the net for rubber moulding companies...I am sure you will find one.

Bert's agreed with my assessment. They don't carry the thicker channel and seems none of the other vendors do either. I looked at many rubber extruders on the web but I could find nothing suitable. And yes I have the thicker roll down style frame.

I think perhaps back in the 80's or earlier they carried them because the one on my car looks as if it was replaced in the 70s when the cosmetic restoration was done.

If anyone knows where to get this thicker rubber U channel for the rear window please let me know

Thanks

Hansen, where are you? I went to a glass shop in Dublin, CA and he had it in stock. He also had owned a coupe so that may account for his having it. I replaced all the plate glass with the laminated glass as I drive this car, when I am not repairing it. Perhaps one of your local glass companies can help.
 
I'm not positive but you might take a look at what is being sold for the 1932 Coupe rear windows. I recently installed the channel for my 32 5 window coupe and had no problems. Ed
 
Thanks to all for the suggestions. Wefco has a large selection of U channel rubber and they have something close to what I need in stock. Thanks Puck

None of the vendors I called we're aware there was a special size U channel for the late 31 coupe. I suppose there were not sufficient cars manufactured to justify carrying this version
