At the top of the grill on 9N and 2N are three pins that align with holes in the bottom of the hood. At the bottom of the grill are the holes that fit over pins on the dogleg extensions to the hood. Those pins are inserted into threaded holes in the doglegs. The holes are 3/8-16 thread. If those pins are missing you can use bolts with the head cut off to replace them. Installation of the grill is accomplished by loosening one of the doglegs from the radiator support. The three pins at the top of the grill are aligned with the matching holes in the bottom of the hood and inserted therein. Then the hole on one side at the bottom of the grill is placed over the pin on the dogleg that is still fastened to the radiator support. Then hole at the bottom of the grill on the other side is aligned with the pin on the loosened dogleg and that dogleg is returned to its proper position and refastened to the radiator support. If you have the early style doglegs (smooth on the outside at the bottom rather than having a hole with a bolt that goes in from the outside) that are attached to the radiator support with "L" shaped brackets, it may be easier to just put bolts in rather than using pins as that type can be real "fun" to attach to the radiator support.
The grill on the 9N and 2N is fixed in position once installed. On the 8N the center pin at the top of the grill is deleted and in place of the center hole on the bottom of the hood there is a "bumper" that prevents the hood from being pushed in too far. The outer two pins at the top of the grill were replaced with spring loaded pins rather than fixed pins. The spring loaded pins have tabs sticking out the front of the grill so you can push them down with your fingers and stops were added at the bottom of the grill where it pivots on the pins in the doglegs to prevent the grill from opening too far. So on the 8N the grill can be easily opened and closed in order to clean the radiator.
