Engine Undertray

[BryRS4]

Hi everyone c:

Recently my front plastic belly tray partially came off on the motorway and has disintegrated while it was dragging on the ground.

I can't seem to find the part number for a replacement as all the google searches come up with the A4/S4 trays without the ducting which goes into the brakes.

Or does anyone have an image of their whole tray intact that I can see so I can get an idea on how feasible it is to fabricate one out of aluminium or stainless steel.

Thanks c:
