Just came upon some of these at a local wally world and there were 3 of the 1958 Plymouth Furys. 2 of them have silver grilles and one had a Gold grille...any info on why some have the silver and this one had the gold grille?

On the tan one it had a gold grille on the real car. All 56-58 Fury's were the same color Buckskin Beige and gold trim. Anything labeled a fury in this year range is labeled wrong should be a Belvedere. 59 and up there was Fury and Sport Fury and could be had in more colors.

The one with a gold grill was from release 5A while the all blue '58 was from 5B. Check out the official site from M2 for official pics and closeups.
