wakedaddy, all of the doors are the same size right! And, I assume you have a 3/4" straight router bit and 1" template guide or a straight bit with guide that will fit the bit.
To begin with we can't use a rabbeting bit to remove the material in the back of the panel door... why? because the panel is in the way. First thing we have to get the panel out of the door, so we can make a 1/4" thick plywood pattern that is the same size as the panel in the existing door. It is usually 3/8" to 1/2" larger than the inside edge on the back...if you need more let me know.
Once we have the pattern made we use double stick tape to position and mount the pattern on the back of the panel door. Next we want to set the depth of the straight bit to match the thickness of the material holding the panel in on the back side of the door.
Using the straight bit and template guide cut out the material on the back side of the panel door and remove the panel from the stile and rail of the door. We now have a frame of the door ready to receive the glass.
Measure the exact size of the opening from the back side and get the glass to match. You might want to go to the glass cutter with your door and let them measure and cut the glass for the doors.
Use silicon to seal in the glass into the door frames.
Hope this was helpful, if you need more info like photos let me know, Rick
