OK, I cant find any details with those numbers, sorry.
If the element isn't held from inside, the older type are held from the rear.
Disconnect the supply
Remove the back cover at the rear of the oven.
You will then see the retaining screws for the element.
Make a note of the wiring and remove the element.
The retaining rod across the ceiling is flexed to pull it out of one of the holes, so enabling you to remove the rod and the element.
If you need more help, please jut ask.
In the meantime,
