scat pack bees

jus got some repop bees for the quarter windows on my 68 gss clone. they are about 2" long. they claim to be exact reproduction. well I am 62 years old and back in the late 60s I used to go check out the new super bees, charger r/t and dart gts and those little bees were like 4" or bigger. anybody have any knowledge on these scat bees.
