hi, i was just spraying my dashboard pieces in my corsa b and removed the center console and fitted the painted one, however when i got to screwing the last screw in before i was finished putting it all back together the end of the screwdriver came off!! and it has gone down the vent!

you can get a flexible extendable magnetic arm to slide through and pick up the screwdriver bit
