This part looks pretty similar to the 996 Turbo version: 99650402900

I guess it can be modified quite easily

 

Ya. I sent him a link to one on eBay for $125 shipped. They look identical.

 

Yes, thanks to you both. I looked at the street GT3 part for 2004/2005 and bought the tray in question. Oddly, th estreet GT3 does NOT have the vents. At the suggestion of several of you, I checked the Turbo PET and I came across the part described above. Pelican has them new (hopefully!), and I have one on order. My Cup is starting to feel like my 73 911S MFI car - most parts are VERY difficult yo come by now! Good grief!

Just received a 996 Turbo version pn 99650402900 of the undertray: The leftside vent has to be cut, the airjack areas have to be cleared and two holes drilled to srew it to the holder on the rear of the gearbox, thats it. Costs under 200$ + some cutting and you'll have a 996.504.029.9B

 

.....here is my modified TT tray to Cup spec
