Shifter nameplate and screw for 105

This is really making me nuts. (At least it's the reason I give my wife
for my insanity. She ain't buying it.)

I had a little spill on my bike 2 weeks ago which scratched and/or
ruined the nameplates on my shifters. Now I am not one to insist the
bike goes on forever in pristine condition, but leaving the assembly
underneath exposed to any subsequent crashes disturbs me.

So I went looking for the replacements and found them to be rather
pricey ($12 per plate at my lbs, and $18 for a pair of them on the web,
including shipping.) We're talking about cheap plastic here, I can live
without the 105 name.

I am missing the screws, too, (I again refer you to my wife for any
opposing theories on loose screws and all issues related to the verb).

Is there a cheaper source or can I make a cover on my own? I really
just want to protect the inner workings of the shifter from any debris
or damage.

This has become one of those things where the principle of the matter
outweighs the monetary value of it.
