I thought I would just thow this out to everyone ,because it has worked so well for me. If you have any Plastic Panels, covers Etc. that need to be trimmed, or a opening cut into ...try this. I have found that using a regular (Tile cutter) from the Hardware Store works Great! All you have to do is strike a straight line ,or curve. Then lightly drag the Tile Cutter back slowly to start. The tile cutter will Cut through the plastic very clean. I used this for my Shifter Base ,Dash and cutting out for my Speaker openings in the Kick Panels. My Factory Grilles fit in Perfect! Hope this Helps...... Kirk
