68 charger rear leaf spring slap

[dodgey68]

i have an annoying rattle in the rear of the car, its taken  a wile to work out what the noise is, i reckoni finally narrowed it down to  the leaf springs, they are the original leaf's,  how can this be rectified do i buy new or will fitting the leaf spring gasket fix the issue,  i used to have lowering blocks, but now its back to standard.
thank you
