Just purchased my 69 out of Michigan. Was in storage for 30 years and is in excellent condition! All original metal and top. White ivory houndstooth interior. Has an early 90's 350 motor with a Tremic 5 speed trans. The car is an SS car, but from what I have read that there were Camaro Convertibles in mid 69 were not given an X code. My Camaro was built the last week of August in 69. So how do I know it's a true SS car?
