I’ve been a Corvette and Muscle Car enthusiast since the 60’s....before I was old enough to drive. In 1973, at the age of 18, I bought this 67 Marina Blue L-79.......second hand. 50+ years later it runs just fine. Back then they were Vettes......Terminology as C-2 or Midyears, had yet to be invented.
I specialize in 'NOS' Corvette Spark Plugs and also have most of the Muscle Car 'NOS' Spark Plugs as well. If there is a specific 'NOS' Spark Plug that you need, that I don't have in eBay.....send me a message.......I may have it.
