fire extinguisher

I am looking to mount a fire extinguisher somewhere under the front drivers seat for access and would welcome any ideas for a mounting kit. Regards Don

The 1kg/2.2lb fire extinguisher that comes in this kit; anyone know where it stores? (I'm hoping under the knees on a front seat, like my Cayenne TSSY) How about the 2 warning triangles, 2 reflective warning vests, and first aid kit; where do those store? Pics would be wonderful if possible...
