Believe it or not , but the one I bought at Autozone works great ( Lifetime warranty too . I don't think the big dent and scratch I got are covered though , LOL ) . Really shouldn't need one if the frontend is in great shape ( or you go crossover like I DREAM of ) , but I run one anyway /forums/images/graemlins/k5.gif /forums/images/graemlins/k5.gif
