A fire extinguisher is the only tool or item I own that has just one purpose.

 Unless one owns a multi task CO2 extinguisher that will also chill beer.

I bought a 2.5lb Kidde unit and mounted it behind the passenger seat by using a 5"x10" piece of 5mm thick black ABS plastic with 4 riv nuts placed to coincide with the fire extinguisher's bracket holes. I placed the ABS base under the carpet and secured it to the floor with 3M heavy duty double stick tape, replaced the carpet and put 4 bolts through the base and carpet into the riv nuts. Finally I placed the extinguisher into it's very secure base.

 

To mount my fire extinguisher I bought something called the Bracketeer.

I mounted it in front of the passenger seat.  It bolts to the factory seat mount bolts.  The clearance is nice.  It does not hinder the movement of the seat.

 

Nice product, quick and easy.

@2377kNthis mount will not fit for a 240Z, right? I can't remember that there is the front part of the seat rail bent down like in your picture..? 

I found a rechargeable First Alert, all metal that fits perfectly in the bin behind the passenger's seat.

 

@german240,

I've never had a chance to check out a 240z interior, so I can't say if the braketeer it will work in one.
