I have a 1977 280SE that I have owned for about 2 years. I have the service CD but I cannot find the version for my car. My reason for wanting to know is:

1. there is no plate or reference to emission controls on the tag.

2. trouble shooting tune up problems refer to EGR service and air pump testing. I have neither.

3. Calif emission testing is due and what standard do they test this to?

The VIN is 11602412068925
