68 Console shifter details, What am I missing???

So, I'm trying to get al of my pieces and parts to fit. Some new and some used.
I just scored this cast aluminum piece that mounts to the bottom of the forward
top plate with four nuts. My problem is the clear plastic lens with "PRND21" fits
on these little pins before you mount it to the top plate. Is that it? You can look
right into the void and see the blue cover for the light bulb. Is there something
else supposed to be under that clear lens? The FSM doesn't help, and I can't find
any pic's on line. Thanks!

You are missing a flat black metal piece under the lens.
