Seems like folks just rarely took pictures back in the 1960s...or the pictures they took haven't survived. I was amazed to see a small photo album of this '68 Impala SS427 for sale including interior shots - would be great to reunite it with the car.
***Tony I added a few pics to your original post which is now 32 pages of amazing pics from back in the day. I'm posting on our website FB page.***
