The glass part does not come with plate warmers. You will have to disconnect all plate warmers from previous glass piece. Also the metal shapes are not exactly the same as the previous one, so you might have to adapt the clip locations in a creative way - they are no instructions. Make sure you take a photo showing all clips before your dismantle the old one, and don't lose pieces rolling to the side of the white insulation below. Definitely easier with 2 persons to do the job(1-2h). This is still an expensive part in the end.
