I have an old 40" electric, self-cleaning GE range (serial number indicates an October 1990 build date). Yesterday, one of the center glass panels in the main over door shattered. I removed and disassembled the door, and found there are four panes of glass in the door. The broken one is second from the interior, and is in a metal frame with the innermost window.

The frame is 16 1/8" x 7 1/8" x 1 1/8" and contained the two pieces of glass sandwiching an internal aluminum frame. I can't see any way to insert a new piece of glass without bending the edges of the outer frame.

I've found the following parts breakdown diagram for my model:

My assumption is that diagram reference #373 (part #WB36X5542) is the full frame and 2 window assembly that I need. Can anyone confirm this? If it's possible to just get a new piece of glass to insert into the existing frame, what's the part number for just that glass? Can anyone recommend a good vendor for the part I need?

Here are pictures of the assembly with the remaining window:
