06Reference
Identification guide
How to tell an original from a replica or later conversion.
The 1970 Riviera is identified by exposed headlamps (the hidden-headlamp design ended after 1969); GS equipment on 1970 cars is described in the cached source only as the performance package with the 455 engine.
