Mercedes R107 ignition control module + ballast resistors

This is a detailed video in which we install the correct ignition components in our 1975 project 280SL. The ignition control module and coil are removed from our rusty 1975 450SL parts car. New ballast resistors are installed along with stainless steel hardware. There is still a ton of work to do before we get this car running, but we are making good progress.
