just curious as to what is a good parallel rear spring for my 39 deluxe coupe. it has parallel 4 leaf with the rear eye reversed now with new gas shocks and i hate the way it rides. sometimes it feels like it just bottoms out when hitting the right dip in the road. and there is hardly any arch to the springs now..i wouldn't mind if it rode a little stiff over hearing that bottoming out THUD at times. thanks for any advice.
