My friends the beer is flowing tonight!!!
After 5 1/2 hours of attacking this fricken bolt I managed to get a slot through the middle, butcher up one of my old wood chisels, file two flats on the handle then carefully unscrew the bolt, this sounds a bit basic but it took 1 hour of hacksawing just to get the slot in it due to access
My car will now officially be called 'the bolt'!!! the fun bit starts now working on a new EFI plenum design to bolt back up to the car
Happy days!!!
