hey everyone

got a problem, there is a problem with my brothers ignition barrel and the car is not turning off..... we have bought a new hole casing and have been told that there is a hole you can push a pin in to and the barell slides out the middle??

we have tried to get the barel out but its just not going anywhere, unsure on what to do as the bolt that holds the ingition casing in is a wierd shape (obviously so people dont just unscrew it) so we cant get that one off without snapping it and we just want to change the barrels

anyone have any info for me??
