Hey all, been looking at a 70 MC SS that does not have a factory tach to the left of the speedo. If I remember correctly, there's a fuel gauge there instead. Since I'm new to these, I have a couple of questions: 1. Was the factory tach considered an option in 1970? 2. If the vehicle did not have a tach, is the wiring still in place for the tach so if someone wanted to change the gauge cluster, they could without changing the entire harness?
Thank you in advance for the help.
