Do not remove the glued the part, it is just plastic piece. Just remove the electronic part and replace it with the new one. The part number you referred above is just the electronic part. If you want to remove the glued part, you have to replace the whole windshield, because it is almost impossible to re-attach the plastic piece back to the windshiled and you will damage the plastic piece when you are removing it. There is no replacement for the plastic piece, only the whole windshield.
