64 Nova SS Rear Suspension

Hello, I have installed your mini subframe kit with upper and lower tubular control arms and coil-overs but am now interested in upgrading the rear suspension. The original mono-leaf and original style shocks are there but what a rough ride... What is the best approach to get a move comfortable road riding car overall? Should the mono-leafs be replaced with multi-leafs and maybe a coil-over of what? I would like to keep the original style setup (leafs and shocks) not go to a full rearend change.

Thanks in advance,

Mike

A set of multi-leafs and a good pair of shocks will do the trick!
