Folks,--I have the gauge cluster out of the '64 Fury and need to remove the plastic that acts as the "glass window" between the outer trim plate and the panel itself. The plastic is attached to the back side of the trim plate. It looks like it is glued or riveted at 8 or 10 contact points.Before I go tearing this thing apart (and breaking it), has anyone done this before, and, if so, what is the trick? Heat gun? M-80s? .45 Auto? Can't imagine I am to drill through plastic...Thank you,Jim
