That area is a hotbed of older cars thief, especially Oldsmobiles. They seem to be finding them stripped out but usually not overly damaged. I know that sounds strange but in the case of the 1967 442 W30, they took the edelbrock headed built 455, Rossler transmission, 12 bolt rearend, the drivetrain had a lot of $$ in it. The left the body in a parking lot. Interior in tack, louvered hood ($$$) was set on the car, I believe the hinges were gone. The rear of the car's body set on cement blocks, yes there was some body damage but nothing compared to "real" butcher car strippers would do. There's been other brands also but they seem to like Olds. Sounds like the busted/ruined the ground effects on this G-body. That will be very hard to replace/repair. I figure theirs got to be at least 3 or 4 of them. Enclosed trailer with winch? Watch craigslist for parts. Jmo
