it's a tight fit trying to "roll out" the grille from the bezel (on 86-87 TR's).
to keep the bezel & surrounding paint from getting all scratched up: after removing the grille's bolts, place masking tape on all the bezel's surfaces where contact might occur.
I like the 3M Blue tape, it leaves no residue if it's removed within a reasonable time (up to a few weeks, as long as it's not exposed to sunlight).
