Re extinguisher, is your car STD or SV I think it might fit across. Caterham fitted it to my car length ways down the foot well)? So your feet went ether side of it
Have not got the car now so cannot go try but here are the dimensions of the extinguisher
390mm long by 110mm in diameter
Hope this helps
p.s if you want this I will let you have the pull handle and stickers as well
Its still snowing *thumbup*
