I scored a set of Marchal lights and was going to install them on my bird since I have the TC header but they are different size than the Hellas that came on the TCs . Has anyone ever made this swap or can it be done?
Sell them and buy an aftermarket set of lights. You'd have to cut the holes larger for the lights. Not worth it. New fog lights make a lot more light than the old Hellas as well. Unless your car is a restoration, no need for the factory fog lights. I had an NOS set of Hellas on the Sport. They are now boxed up and a new set of modern driving lights (same size as the Hellas) are now installed. WAY better results.
