Firewall pad plastic plug removal

[Lynn]

All the ones I have encountered on 69 Camaros were rubber. If hard, like plastic, they are probably already a lost cause. It is what it is.

If soft enough to remove, I have had luck lubing with dishwasher soap from the inside, then squeezing the sides and pushing it out. Only did that on a couple and it was many years ago. At 50 years old, don't know that any would be pliable enough to get out now.
