shark tooth grill molding

Hey everyone, I have a 71 duster and I have a lead for a shark tooth grill and I was wonering if the crome trim from the stock grill will have to be used. when I saw they Sharktooth grill I dont think it had a chrome molding on the top or bottom. Do they use it? I know I need to use the headlight bezels from my grill and I know the parking lights are different. So what else to I need to make this work
