hi, i have a 96 blazer-s-10 2 door. It is the sport whatever, anyway, I have 3 type r's in my trunk and my car rattles like shit. Even when my music is off, something in the rear of the car rattles. Has anyone experienced this on a blazer? So I wanna possibly put like weatherstripping around the glass on the rear window adn dynamat the hatch. Has anyone dynamated a blazer before? where to begin? How effective do you think this will be? ANy suggestions would be helpful. THanks.
