1968 Dart GTS bling...
I have the same from my 67 Dart Convert.
The original 67 tag was under 2 or 3 other tags and I picked them off with my finger nail (felt like bamboo under your finger nails)
Before 70 something all tags were due on Jan 1 of each year (or something like that) so there was no month sticker.
Each year the new tag went on the opposite side.
Odd years on the left even on the right.
Since yours is a 68 the 68 tag MIGHT be under the 92.
Under the month there should be a 69 tag maybe even a 71. Since the month sticker never changed the likelihood of the 69 tag being there and in good shape is high
Happy picking
