Quick question on the dash pad for a 87 chevette. How does it come off? I need to replace the speaker. Idealy, I would like to install two speakers in the dash, if there is room I found six screws, one in each end, two in the guage cluster, and one each in the defrost vents. Took those six out, and the pad seemed to have a little give, but also acted like there were more screws involved.
