Hood scoop chrome

My 72 swinger had scoops added before i got it. Im looking for the chrome
Trim that goes on the front. Is there a diffenece between a/b/e body scoops? I came across this on ebay and looks like what i need. If they are all different how would i ascertain what scoops i have as prior owner couldve used wrong scoop. Thanks in advance.
