[Bill Pritchard]

The title will most likely be of no help here. With a 70 Chevelle, the best way to know how the car was originally equipped from the factory is to have one or more of the following items:

1. Documented owner history.
2. Assembly line build sheet (these are readily & regularly faked so it takes someone pretty knowledgeable to tell if it's real or a fake)
3. Original warranty card, commonly known as a Protecto-Plate (same comments about the build sheet apply here).

Without those, it's extremely difficult if not impossible.
