nope ... all i did was remove all the plastic leading to vents for the heat/air condition, i bought a piece of mdf board and screwed the clips on from the factory vent piece to the mdf, fiberglassed it, cut out my piece for the cd player and turbo timer above it. i have yet to have a crack or anything on it. its been this way for about 8 months now. it pops right in and out with clips just like the factry piece. i also fabricated up a bracket behind the mdf to hold the cd player properly so it woldnt sag down to cause cracking ... took all about 2-3 hours to make and paint it up. looks smooth too! :)
