3.8L exhaust hangers

[68bird]

My buddy has a 3.8L fourth gen and he switched to magnaflo dual exhaust, but some how he broke the hangers, so i'm trying to get him the stainless steel ones but i don't know how big they have to be. Can any one tell me how long they have to be?

If it helps im going to try and get them from Summit Racing and they come in 4", 7", and 9"
