67 barracuda dash light replacement

I have a couple light bulbs out so I thought Ide replace with led How the hell do you get to them I got the one all the way to left drivers side but cant even feel the others am Imissing something or is it impossible to do?

There are 4 that illuminate the dash. The one you found, then there is 1 on each side of the small center gauge, clock, vacuum or whatever and then the last one is on the far right side. You will feel other bulb holders but they are not for dash illumination.

Tried to find a pic of the back of the dash but didn't have one. Maybe someone can post up a pic of the back side.
