The car is pretty far from stock, but I am amazed what some people on the site are able to do. Actually My dad bought this car in the San Diego area, so although I live in Norcal now, not sure about how it came to be in Socal. We were not able to locate the build sheets or anything else when the car was painted silver. Pretty sure the interior was cobbled together, looks to have a blue lower dash pad, and it had green seats, steering wheel, and A-piller covers. It did had the trunk decor piece, although it is gone now.

Thanks for the info on Omaha Orange - I read through those posts. Very interesting...

I found some numbers in the trunk, but they do not seem right. Are there numbers on both the drivers side and the passenger side? I think I am looking in the wrong place.

Drivers side - 2841301
Passengers side - 2841300
