Window Channel Felts from Classic Parts

[Bob Q]

I got the replacement window channels for my '83 from Classic Parts and got the passenger side installed tonight. The installation went pretty well, but then when I went to crank the window up for the first time for a test run, it would go up about 3/4 of the way and get super tight. The window adjustments are the same as they've always been and I know it's going to be somewhat stiffer with the new felt, but this is way too tight. Anyone else use the new channel felts from Classic Parts?

Thanks.
