installing white face gauges on 89

ok i baught these white reverse gauges for my 89 and it didnt come with any installations instructions.
i seem to have one problem and that is removing the light pop up part with the big buttons.
i dono if i have to remove the whole entire dash to get that part off or not.
if anyone can help that would be great.
thanks.

you have to drop the steering column to get access to the instrument panel.

I wanna see some pics of this when it’s finished. I’m thinking of doing the same thing!
