Here is my project 53,000 mile one owner 1966 Holiday Coupe Cutlass w/ a 4th week Aug 1966 build date. It has the interior, 12 bolt rearend and 67 Aircleaner as a carry over from the laet production date. My dad and I got the car in 96, he passed in OCT 96 and I have it barned on my ranch in storage until I feel like tearing into it.
