1965 Dodge Dart Charger

Late last night I tried to mount the upper part of the back seat. But there is a gap between the seat and the body! I tried to adjust the hooks where the back seat is hanged on but it didn't turn out better.

Is the solution to bend the bracker on the back seat so it gets closer to the body? It looks weired when you see between the body and the seat back.:banghead:
