I agree about the customer service with JConcepts. I had an original and bought a conversion kit that was short 2 screws, and I told him I could have lost them and am willing to pay for them. Well,the NEXT DAY the *whole* hardware set was in my mailbox. I love JConcepts!! I love the bodies, so slick and aerodynamic I know its faster, maybe not a lot but hey it works. Thanks for throwing this thread up.
