I'm in the process of installing a new set or rear leafs (4) on my Mav. Since every other piece of rubber under the car is being replaced with polyurethane bushings, I'd like to use them on the leaf springs too. Anyone had any success finding some? While on the subject; Craig, weren't you putting PST bushings on you Mav? If I'm correct about this, how 'bout an update on the install process and a performance evaluation, if you are back on the road. Thanks either way. John B.
