When someone asks when was the first year for factory turn signals. Do you think they mean clamp on GM and other companies add on accessory turn signals? or do you think they mean factory integrated turn signals? In his second post he sees that 54 was the first year for what he meant. So therefore he did get the answer to no. 2 already as I said. You proceeded to confuse the issue with GM factory, GM (the factory), Factory accessory, self cancelling and clamp on. Which I read every bit of and was confused. Was asking for clarification. A GM accessory is not Factory in the usual sense. They had accessory catalogs at the dealers and you could buy from the dealer and have things installed. Read all that slowly. Bartamos, poltergeist.
