One thing that I look for, all though it could have been replaced, is the fact there is no medallion on the brake pedal for power brakes. I view this like fuel lines in that is one item not usually touched or changed when converting to Pwr. brakes. It does show evidence of RS based on wiper motor and holes on inner fender where washer bottle was located on RS car. If you really want a true BB car, there are many details not present under the hood that would probably keep me from seriously considering this car as authentic. My 2cents.
