This is a somewhat silly project that has started to take on a life of it's own, so I thought I'd try to assemble all the information in one place should anyone else wish to add factory option M509 to their 996.
This is the diagram showing a 996 sport seat and the bracket, cradle and associated fixings:
And this is an (incomplete) parts list:
999 141 028 02 x 3 = screws to mount metal bracket to seat frame
996 521 674 00 (LHD) or 996 521 673 00 (RHD) x 1 = metal mounting bracket
900 067 137 02 x 2 screws to mount extinguisher cradle to metal bracket
900 151 027 02 x 2 washers for the above screws
996 521 607 00 x 1 Plastic red cradle to hold extinguisher
What is missing from this list is identified as part 17 on the diagram - you'll need two of these, they're little metal clips that are threaded, and are needed in order to attach the cradle to the bracket.
Always fun getting your order in a thousand small plastic bags:
And here's the expensive part:
Which, when you receive it, you'll note is a Mercedes-Benz part:
This is important, and will help later!
Here's the bracket that fits to the seat, with the Torx headed bolts in place:
They're T25 for reference:
The cradle is retained by both a hook and some bolts:
Said bolts should locate/fasten into 2xpart 17 from the exploded diagram, which currently I don't have:
