What work on car?
You will need to be a member b4 you get cams licence.
I am not a committee person, so sheck with bec, Snowman, Adzmax, R31_Nismoid, etc.
I'm fairly sure the answer is no.
If you get the right extinguisher (1kg from memory) with the metal bracket, you remove the bolt holding down the rear seat in the rear footwell & bolt in the fire ext. bracket there. I did mine on passenger side so easier to access if req'd. it's also out of the way for ppl. Think it was around a 12mm bolt in my R34.
