Topper sliding window channel

[4X4HIGH]

I need a source for new window channel rubber for the sliding windows on my topper. Mine have become very brittle and broke apart. My Blazer sat for 3 years and I'm resurrecting it at the moment a d I'd like to get these windows back to working order so they will open. Does anyone have a source for new or good used pieces?

Good Luck. I ended up measuring the channel, and thickness of window. Then looking for the infamous universal window channel moulding. This is what I purchased

I had to relief cut at the front corners of the opening or the seal pinched closed to prevent the window from closing completely. I still have to mess with the seal at the front inside edge if I open them and want to close them tight. After they are open long enough the rubber just closes. It does keep the water out though.

I did not glue it in, had I done so, I don’t think I would have to mess with the front edge like I said above. I would glue the sides not the bottom.

I got tired of looking and needed something, and that was the closest I could find to the original at the time. A seal with more of a squared up base, and of course the correct width would probably work better. I was able to insert the seal without removing the window, didn’t see a way around it.
