70 'Cuda's had the 'Cuda script pt#3446960 adhered with tape, usually centred between the license plate opening and the trunk keyhole.
70 Barracuda's had a rectangular badge, with Barracuda spelled out inside it pt#2786559 secured with two pins with nuts on the inside behind the trunk lock protector shield.
Are the two holes in line with the trunk lock key hole?
If the holes are lower down, some dealers drilled holes to attach their name plates. Ive seen dealer name plates on both sides of the tail panel.
Hope this helps.
