1969 Race Dart w/ 426 Hemi- garaged for 45+ years

Not sure what you mean by "original condition". The door panels are from a Swinger, but not sure if it was a 340 swinger, by the "DART" name plates on the front fenders. It does have the shoulder belts as a 340 would. The grill is painted as a swinger. The seats are from a Dodge Van, as was the 68' Dart Hemi. Funny how the hood inner supports were removed, but the rear seat was still there, as the 68' Hemi had no rear seat. The roll cage is also added to the original car. Original, as in a "set up" race car from the day, is awesome!!!! I agree, leave it as is.
The vin starts with "LM23P" so that is a swinger. According to the fender tag, it has almost no options, and appears to be "stripe delete" also.
