'70-'71 Dart front side marker lamp (bulb replacement)

I just noticed the lamp is burnt out on the driver front fender of my '71 Dart GT. I crawled under it to see how it comes out. I wiggled it, pulled it and twisted it but it didn't budge. So, instead of breaking something, I thought I'd ask for guidance.

In my Google search, it looks to me that the bulb's socket is a push-in/pull-out type similar to these:

Can anyone confirm?

If this is not the case, what then?
