Rear left bedroom window seal.

[Glen Even]

I have a 1975 Palm Beach & I’m replacing window rubber seals. I did the L. Couch sliding window. Cut the one positioning tab into 3 pieces & used them all.
But my rear bedroom sliding window has no positioning tab to cut to hold the window up when I fix it into the channel.
Suggestions on what to do? Are they about
1/32?

When I did my rear windows, I had them out and on my bench. I positioned two tongue depressors on top, side and bottom. That evenly spaced out the window in the channel.
Itas a good snug fit on bottom and top.
