1970 grille on 1971 truck HELP

[01chevduramax]

I remember reading a thread about this a year ago or so. I searched for it but can't find it. I recall reading that I would need a couple different brackets for this. Anybody know which ones I need?

I need to pick up the inner/outer grille. Who makes the best reproduction? A friend of mine has the smooth outer with stickers, it looks alright. I found some with stamped and painted letters for $550 or so. (Eckler's)

Thanks
