My ESPO replacement springs started wheel hopping after I swapped T56 Magnum 6 speed.
So I clamped the forward most two leaf springs which solved majority of it. On some surfaces no wheel hop, other surfaces a minor shutter barely noticable.
So decided to take some 1/4 inch plate and reinforce the top leaf spring further. That should prevent that top leaf from flexing. The plate has a slight bend to hug the curve of the leaf spring.
