Hi Dave
Yes, you were right about the part number for the main top. In the AppliancePartsPros.com data base the part number for this main top is
AP2125476.
It is not very complicated job to replace it. You, probably, will need somebody to give you a hand.
To start, remove the screws from the front of the main top holding it to the frame and lift it up. All burners are attached to the main top. Remove them one at a time, remove the indicator lights (they have the locking clips) and then release the main top from the hinges (under the control panel) and remove it.
Assemble all parts in the reverse order.

Good luck.
