Redoing my carpet....  1964 Chevy Impala SS 2dr Hardtop.  I CANNOT REMOVE THIS BACKSEAT.  I looked under the backseat (from inside about 1 inch from the floor) and noticed a clip that I need to push back then pull up towards the car.  But I tried and tried, even used a dam hammer.  Is there a seat belt bolt somewhere  (I have no seatbelts in the backseat, so cannot trace it) - or is there a set of bolts somewhere (like the front buckets) that hold the seat down????     ......If anyone knows, I would greatly appreciate it.  My sincerest regards, and thanks.
