Not my car but....
Was doing a flood damage repair on a buds '70 Duster (Bought new by his mom).
When I pulled the carpet out there was a roll of 1964 Kennedy half Dollars. Go figure.
Not an A body... When tearing down the interior of my '71 GTX the first thing I found was 4 new T handle shifters with 1 still in the Mopar box!
They were stuffed up in the console.
Then when I pulled the carpet out I found a complete joint laying on the floor.
Smoked it with a couple friends.
Nasty but still got a buzz. LOL
Later,
