My perfex kit was sent out today and they told me to not freak out when the box says fits only 450's. They said it will fit my 500 just fine. SOOO what else off a 450 fit's a 500? Did they change the frame and everything or just the body??? I'm going to be pissed if it's so because the bumper I just ordered for $90.00 is going on ebay for $40.00 but it's for the 450. Does anyone know what's what?
