I just put a new trunk-lid on my 72 Charger SE and the trunk lock hole is bigger and the lock is held in place with a nut instead of the clip on my old one. Do I have a 73 lid, did they change the dia. of the lock cylinder from 72 to 73?

 

Found out the trunk lock dia. is larger for 73 and 74 Chargers than 71 and 72 Also the 3 and 4's are held in place with a nut instead of the C-clip
