George G, char broil sell's a cast iron grate for the G A and I believe it's even expandable for other size grills. Think it was around 20 bucks at wally world.
I like it. I'll probably grill something on it this evening.
I also need make a simple steel rod pick up tool for the grate . I don't want to jam something between the ribs to pick up as I've seen ribs crack by doing so.
