What rear suspension is this?

look like lakewood slapper bars of the universal fitmnet variety
installed too far back

replace the front snubber with a Abody lower arm snubber which is shorter and less likley to snap off.

move em forwards so they hit the spring eye
use something to space them down at the rear mounting point...1/2 -1 inch inch of steel plate with holes for the U bolt
so that the bar is parallel with the ground

i'm presueming your's use the the squred off U bolt universal mounting rather than the bolt to the lower shock plate mounting.

and they will work more or less as intended

if you get good springs and a pinion snubber you can achive much the same and its probably the proper way to do things

if you have crap springs and no adjustable pinion snubber these will help.

lots of people hate them but they do actually kinda work. if you have enough power to wrap your springs into a vague S shape putting these on tends to stop that and the associated wheel hop.

at its most basic its a band aid to allow a bit of track action in a street car
