I need part number for the top oven elements D906 G11?

My oven has blown the inner top element inside the oven. I need a part number for the 2 top elements in the Delongi oven model D906 G11 so I can order the elements. It is the smaller inner element that has blown. My service provider does not stock delongi parts and will have to send someone out to get the element which will cost me heaps as I live 30km from town. So I want to give them a part number so they can order it and then come out to fix it.
