When i bought my 72 roadrunner (clone) many years ago, i discovered that the previous owner had zip tied the center section of the grille down to the bumper itself. I did some research and eventually acquired all the necessary brackets and purchased a hardware kit off of ebay (i believe).

Ive managed to figure out where everything goes, except the plastic "washers" or bushings if you will. Can someone please tell me the correct location/position these plastic pieces are to be installed??

Im pretty confident that one is for along the top of the bracket and the other is for the bottom. But which is which?? One has a larger hole and the other has a smaller hole.
Im also confident that the barbed retainer sits on top of the center grille section, and installs facing down. like so...

Then, im assuming one of the plastic bushings goes in between the grille and the bracket? but even though it looks like a bushing should be there, the barbed retainer doesnt look nearly long enough to me. Another observation i made was that the barbed piece can only fit through the bushing with the larger hole, but is not snug through the hole. And conversly the barbed piece will not pass thru the spacer with the small hole.
Im sorry for the long post, im just trying to provide as much info and details as i possibly can.
Any and all help would be greatly appreciated! thanx
