Maserati 3500 GT : Changing old to new. You can fix it with a 123 Ignition Conversions unit installed. The 123 Ignition unit will be build into the old housing for a more conventional look. Beside that we are sure that all is fitting with the motor and nothing has to be changed or repossitioned. Reliable starts from now and no suffer about the ignition. Do you have special wishes? please contact us for your questions.
