Are you talking about the lights in the c-pillar? above the backs seat on both sides? if so when I pulled the ones on my 68 they just snap in. A real thin tool, I think I used a small knife and they pop right out. They are in there much the same as a hubcap.
That did it. It seems like everything comes off differently so without knowing I'm afraid of breaking something or in this case tearing the headliner especially with all the knowledge on the site to pull from. Thanks again!
