Water in the rear seat footwell -Roof water drain cover part number?

[Pipemaster]

I have a 2006 SL350 and have had water ingress into mainly the passenger (left) side rear foot well. Opening the roof half way I used an airline to blow out the drains from the gulley near the c-pillar. On one side there is a metal plate with a self tapping screw fixing it in place. The end of the plate has a convex strap over a hole which site over the drain itself I assume to stop debris going into the hole and blocking it
On the other this was missing leaving hole (for the self tapper) and no cover for the drain which was blocked.
I would like to get a hold of a cover to replace the missing one does anyone know the part number or the right name for this pesky part?

Thanks in advance

Stay safe

I would have a trawl through 7Zap- Mercedes - it's a copy of the old MB EPC. Might take a while but you will find it eventually on there!
