1975 Dart SE

Hello,

New to this forum, i'm owning a 1975 Dodge Dart Special Edition and since I have those universal wheel with slugs they look nice but shaky I would like to get rid of them and put Rally Wheel instead like most Mopar owner has, i'm debating between wich bolt pattern I have !

I've searched the internet found that there is 4x5 or 4.5x5 ! When I measure from outside of the lugnut to the center of the other one i'm at 4.25... so wich one it has to be ?

Thank you for taking the time to clear me out on this !
