It's getting less ugly. We have a nice 60 degree November day (I
love that global warming!) and I took the day off because I had a rare chance to (usually I just can't even though I've got loads of vacation time built up).
Test-fitting what I think are the final cuts:
I'm now putting coats of Plasti-Dip spray on them and then maybe tomorrow or this weekend I'll be able to mount them. They fit pretty tight, so I've decided that I'll pad any empty space with styrofoam (as I thought before) and then just face-screw them into the grille. That ought to be good enough if I place my screws neatly.
I could also wrap the edges with some trim, such as door edge protectors, but I think it will be acceptable without doing that.
I also entirely removed the grille assembly from the truck and now I'll be able to work on that indoors when it's cold and dark out.
