Question about Original 1970 Cuda Rubber Bumpers ?

[anlauto]

With Elastomeric bumpers having been in reproduction for over 30 years now, likely closer to 35.....How can you tell if you're looking at an original bumper from the factory, or just an older reproduction ?

Did the originals have any tell tale markings, part numbers or Pentastars vs what's found on the reproductions ?

@Chryco having purchased the original reproduction materials from the original source Gene Gregory, do you have any input ?

Nobody knows how to identify original bumpers ?
