As far as the bumper goes for you to use a bumper off a 73 you will need fenders from a 73 also to work properly. JMO but IMO i would want a bumper from a 71/72 on my car due to the size change in the bumpers in 73. JMO
With this being said to the "OP" yes you can use the grill from the 73 , but you will need a bumper from a 71 or 72 for your car, and to use a 73 bumper and for it to fit properly you will need 73 fenders also along with the bumper.JMO
