You can get the clamp kits at O"Reilly or AZone, its a 2 pack & around 15 bucks, if all you have on the front are the factory clamps Hum... (straps), they will not work, you need to literly "CLAMP" the springs tight, i would also try putting the snubber right on the floor with you in it, if clamping the springs, adj. the pinion angle, making sure the shocks are long enough & the rear shackles are angled right doesn't work, then i'd get some SS springs are C-tracs.
