I have for sale a New Old Stock GM cigarette lighter, part number 7030711. I bought this at a swap meet a number of years ago for a 2nd generation Firebird I was restoring. When I got home, I realized that the knob was not the same as my original. After talking to some people who worked atdid business with GM parts departments back in the day, I was told that it was pretty common for GM to sell a part as a new replacement for multiple applications even if it was not visually correct for all of those applications. According to many of the reproduction parts companies, this part number is the one for many 2nd generation Firebirds and trans Ams. Im not sure if there is a way to put the correct knob on this lighter or not.$50Thanks
