Correct, 97 was the only year of the liftable tag.
David, I have the black box and will look in there for any info on the tag
Rich,
That's really interesting! The 98 I drove did NOT have a liftable tag. I was told by a 97 owner that that was the only year of the liftable. I wonder if the 98 was a 1 off, or your 99??
