2005 T@b T2 Window Replacement

KB_TAB_T2

It's been awhile since have been here or commented/asked a question but I have searched all around his site and the internet but have been unable to find the answer to this question.
the struts (I am guessing that is what they are called) (the pieces that hold open the windows are broken) so we are wanting to just go ahead and replace both windows (frames also) they measure 900mm (35.54 inches) x 450mm (17.71 inches).  But in my search, I cannot find anything near enough to that size that I can make it work.
I feel like there was a thread at one point that talked about replacing the old T@b T2 or at least pre 2010 windows but the threads I found don't have the info I am looking for. 
Anyone have any words of wisdom for me?
Thank you, 
Bryan
