i had a hell of a time finding an ignition that would fit. i even took a picture of the ignition plug and took it into all of the parts stores in my area (including the chevy and GM dealers) no one had anything that would plug right in. there was one close match but it was $130.00.
i ended up calling ez wiring and asked what model ignition i should ask for to simplify things. the guy said i should just cut off the plug and buy a $12 ingnition swith. thats what i did, and all is well. the chevy and GM dealers were adament about how almost every models ignition switch is different.
