Quoted from LargemouthAss:
I bought one and it is perfect!
That backglass on Marco's looks like the '81 version and your machine is the '81 version. One good indicator of that is the silver lift bar on the bottom of your installed backglass in your pix....1981 models lift out. The '84 EBD door swings open with the backglass installed and it slides out once the door is open (nice design, IMO, and convenient for quick backbox maintenance).
The dimensions of the 1984 EBD backglass are different and thus much harder to find. I also sent the dimensions of my '84 backglass to CPR last year to aid in their reproduction efforts. Fortunately I don't need one...my original is about a 9 out of 10.
