Lotek gauge holder screew covers

I know this is silly but here it goes. I installed 2 months ago a lotek gauge holder on my GTP to display OIL PSI, BOOST and VOLTS. From time to time the screw covers fell and I reinstalled them. I expected them to be magnetic or something similar because they are just snapped in place.
Now I lost one of them and the cockpit looks crappy with the screw showing. Anyone has ideas as where I can find this screw covers.
I already went to http://www.gaugepod.com and ask them for replacements no reply yet. I f any of you people know about this I would really appreciate your feedback on this.

I took care of it. Bought black screes and will not use the caps anymore. THe dials are black so they will look nice.
