Its not difficult to convert to a regular chevelle. I believe the major difference is the taillight trim. Grind away the Ss badge on the front fender. Theres also a box thing under the dashboard. Get rid of that too. Its dials for a special stereo system that those cars had. And don't forget to grind the speakers off the parcel shelf. But you NEED the photoetched kit. It has the proper taillights trim piece.
