03-04 Rear bumper with diffuser schematic?

[mikesz]

anyone know where i can find a schematic of an 03-04 boxster rear bumper with diffuser? I am looking for the aluminum trim pieces. One of mine is damaged and want to find out how much to replace it. I am looking for the schematic so I can check on price for new part.

My original thought was "why not look in the PET".  And then I did and the rear bumper assembly isn't there that I can find.

Do you have a photo of which part you are calling the diffuser?

I recently upgraded my 2000 Boxster rear bumper to the 2003-2004 look.  Here is a picture of the bumper I bought with the diffuser

 

 

The parts catalog does not show the 2003-2004 bumper but does differentiate the parts by the model year.

 

The only part that I am aware of that attaches to the bumper is the heat protection above the muffler tip.  It is part number 38 in this diagram and part number 986 505 811 02 for the 2003-2004 bumpers

upon closer look, you might be referring to number 5, see diagram.  

 

 

There are different part numbers for the 03-04 cars. My bumper did not come with these supports.  Now you got me going.

PET also indicates a different popup spoiler for 2003-4 cars ... is this required to match that bumper?

 

Also, FWIW, most publications indicate the styling slots in the newer bumper are included to aid cooling of the muffler, as the engines are more powerful than previous cars.  Not really the usual aerodynamic purpose of "diffuser," that is.

thanks all for your help. the schematic below was a big help. fortunately the pieces were not damaged as I had thought. Somebody painted over them!
