Window Replacement

I never thought I'd be able to report this back. My foamie has survived 8 seasons of camping!!!
I would like to add it's still going strong, but alas, it has several things that need to be addressed. On our roadtrip up to Idaho this year, we pulled into a campsite to find our front window smashed to a million pieces. The front window is a tinted slider, exit window. 42x22". The fixed pane is the pane that broke. We managed to go the rest of the year with pink foam replacement. But now I'm hoping to fix it up to get a 9th season out of my trailer.
The primary issue is that I installed it without a trim ring/frame. The window was used from ebay, and never came with one. So I just screwed through the window into some 1x2 braces and gorilla glued the heck out of it. I'm afraid I will ruin the teardrop if I have to cut out the entire window, frame and all and replace it. I called a few places in the summer to see about getting it fixed, but no one answered my inquiries due to the crazy camper demand of 2020.
So, does anyone know if it is possible to keep my current window frame, and replace only the broken fixed pane? If so, what companies could I purchase pre-cut safety tinted glass from? And does anyone have any resources on how I could install myself?
Along the same lines, I'm also having a difficult time even finding a full on window replacement of the same dimensions. I've only found RecPro anyone know of other options?
