for a good portion of the day i have been trying to unjam a jammed ignition tumbler. i have sprayed wd 40, tapped it with a hammer, jiggled the key while turning the steering wheel in small increments but no luck. the ignition housing hs a special cable for the transmission lockout which i think is getting in the way besides a locked steering wheel. Besides drilling whatelse can i try?
