01 bullitt shocks/springs. Did a fun autox few weeks ago & started hearing clunks--alignment guy says my left bullitt shock is blown (and the right leaking). So time for new units. It appears there's no direct replacements available-were these shocks specifically tuned to the springs? Will the dampening be correct using some Koni sports or get adjustables or B6s? Last I found spring are rated 600#/250# rear. (it's a light autox, street car). Do I just chuck these shock/springs and go with something else? I do like the ride height--just barely below level on the A-arms, no isos (never had a NVH issue), handled great.
