Looking for replacement 930 tail mesh inserts

[moparrob]

So the 930 tea tray rear wing I bought did not come with the original vent grilles and I want to find some replacements.

The original parts are almost $200.00 each for the mesh grilles and I assume there must be a more cost effective way to accomplish this effect.

This is what they look like:





They are part numbers 19 and 20 in this exploded view:





Does anyone have the stock dimensions or has anyone fabricated these grilles themselves? If so, what material is closest to the stock dimensions?

All help is appreciated. Thanks in advance.
