I just recieved my first order from AMEs tonight. I ordered 2 partial floor pans and the rear deck filler panel. I have no idea what the part they sent me for the filler panel is. Its made out of plastic and shaped like the top of the radiator support. I ordered 2 partial floor pans and paid 2 differt shipping charges but they shipped them in the same box?. Is it normal 2 charge 2 shipping cost while shipping in the same box?
