Here's what I wrote recently while trying to fix my windows, after an exhaustive
search to find replacement vinyl:

To clarify, JimK did not have the vinyl channel, just the fuzzy channel for the sliding portions.
If he's out, you can also get the fuzzy stuff from vintage trailer supply:

For the fixed glass, I used some 2mm glass setting tape, and it seems to work fine. I found
with non-adhesive tape, it was easiest to fold the tape into the vinyl, wet the glass, slide it in,
then trim the tape after assembly. However, the vertical channel at the upper front of the cockpit
windows is a weird thing. All the rest of that upper window channel fits the 2mm tape ok, but the
front channel is wider. You can either stuff extra setting tape in the gap, or use some black
rtv to fill it in. Or maybe some of the fuzzy channel would work there, but I didn't try that.
I did have a bit of a "duh" moment the other day... I was sitting in the beast watching
water continue to run in despite having rebuilt the window. Then I realized: the front bottom
corner of the cockpit windows is a problem. Both the window frame and the rubber channel
join there, leaving a big gap for water to collect and pour in. I put a gob of rtv in
the (dried out) corner, smooshed it in with my finger to get it into the gap, put some more
in for good measure, then put the fuzzy channel back in place. Much less leakage now.
Also, some folks recently suggested punching round holes at the ends of the slits you have
to cut in the fuzzy channel to open to the drain holes. I found a regular paper punch worked
for this.
