Should have done this ages ago, fitted a small car fire extinguisher on the seat back between the seats for very easy access.
Have invested in a new gear knob and it has a secret function .....it is a wimpey passenger ejection seat button
cleverly disguised as an engine start button, the pyro's I bought from the North East Aircraft Museum and are good for 100ft.... need your own chute tho....this was another reason for fitting the fire extinguisher
