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

> The glass is between 3/16" and 7/32" thick -- approx 5mm.
>
> The glazing vinyl channel I referred to previously is not the right size.
>
> I think the answer will be 5/64" thick (approx 2mm) glass setting tape.

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:
http://www.vintagetrailersupply.com/Airstream_Motorhome_Window_Channel_p/vts-278.htm

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.

I had an e-mail from Jim B a few weeks ago about the window gaskets. He put together a list of what I'll need and pricing. Please note - I haven't ordered it yet, so I don't have first hand experience, but I intend to order it and then have some fun wearing out my thumbs. Then I'll have to hit the space bar with a different finger.

Larry,
I got my son-in-laws to do the painful work. And they did it gladly.
Cost of going to all those NASCAR events. Got the supplies from Jim B.
There are a number of pictures of the process in the GMC Photo Album.

Be sure and order Jim's thumbs with the stuff. They don't come cheep
though, but they are handy and they don't seem to wear out as fast as
ours.

I'm looking through the photo site for something about doing the gaskets but can't find anything. Do you know where the album is that shows the process?

Here is the gallery I have been looking at:

I'm hoping to tackle this as well once the rain quits for a bit.

Around the end of December I asked Jim B about the window rubber and
he sent me a note with pricing and also this:

"Go to my web site www.gmccoop.com and look on the information page
for "So you want to replace your window rubbers". it is a short info/
entertainment on ho to do the work you are looking to do. You can
call me also as you work and I can help. Let me know if you need
these materials, we have them in stock."

I hope this helps.
