firebrid ?? I believe that the 4 leaf are the "correct" ones. I have 5 leaf on mine and it sits up real good and that's how I like it. Because originally the birds sorta sagged in the back. I think the best place to get them from would be eaton spring here in Detroit, Mi They do have a website. That's where year one gets 'em from. I just pulled mine this past year and had them all powdercoated they look good.
