Mine is on a decal above the headlight switch. I've seen macco spray right over this panel, so you might not have the tag anymore, starting in '79 or '80 they put a tag bracket above the wiper motor on the windshield...
A securtiy guard at an auto repo yard (had to go to pick up a friends jeep who's check got lost in the mail) was about to call the police BC I've 'removed' the bracket the vin plate is rivited to. After explaning a few times that my year jeep doesn't have one, I showed him the sticker / decal, which finally shut him up... - just a story.
