I knew someone out there had faced this problem before.
The other forum supplied the answer and I would like to pass it one here.
There is a plastic runner in both the top and bottom channel of the frame for the sliding window.
This runner can be hooked and pulled out to supply the room to set the glass in place.
Now all I have to do is take the measurement to a glass shop, get the piece made and put it in place.
No need for pesky vendors.
(I would cut the glass, but this is safety glass, a skill I do not have.)
Guys, if you post a question, please, when you get the answer post that as well so we can all learn.
Thanks
