I needed the lower grill housing for my Brinkmann Grill King Deluxe. I ordered 600-3201-0. My old part measures 17 1/4 by 35 inches. The part I received measures 32 1/2 by 17 1/4. I have called Brinkmann and was informed there were only two Grill kings made. 810-3200-0 and 810-3210-0. From my research I think I have 810-3200-0. Where do I find Brinkmann's parts specifications?
