75 dart tailight panel swap

Hey everyone,new to the site. Lots of great info on here ! Anyways I just found a real good deal on a 75 dart. I have had many a bodies before and have never cared for the look of the late ones. I know swapping the nose isnt a big deal. As far as the tailight panel goes can I go to the 68-69 style or do I have to stay 70-73 ?? From what I have read the 70-73 swap isnt too bad but I wasnt sure if the 68-69 tailight panel would go in ?? Any help is appreciated. Thanks everyone.
