86 monte ss

Since the new motor, dash or windshield has been making a squeaking noise. Usually a bump triggers the noise. Any suggestions on what exactly it is? where its coming from? or how to fix? thanks

Im trying to get the woodgrain dash plate on the pass side of my 86 ss. It seems to have a clip of some sort in about the center but it dont seem to loosen it up much. Any help would be welcome i dont want to break it its in good condition! Thanks
