1969 Barracuda Convertible resto-mod project

Worked on the car yesterday and made some progress. Got the rest of the front body panels on and the brand new grills (man - those things are nice!!!).

I have questions:

1) How do you get the plastic headlight trim rings on with the grill in place? I tried with and without the grill installed and it seems like either way the grill is going to scratch the trim rings pretty bad.

2) What holds the grill to the front nose metal piece? There are 9 "rods" that locate each grill to the metal nose piece. Are there supposed to be push clips/nuts that thread on to these rods?

Here are a few before and after pictures.
