Thermador oven Broil Element no longer available
I need a Broil Element made by Bosch for a Thermador cmt-21 UPPER OVEN, part #484776. Bosch has discontinued this part and it is no longer available. Is there any other part that I can subsitiute. I have looked at Bosch broil element part #484777 which is missing the centering plates that fasten to the back wall of the oven.
