AHY 33 Diplomat oven door

I took the oven door off this morning to clean my oven, propped it up against an adjacent cupboard, but the door fell, handle side down, and the outer glass shattered – under the layers of vinyl and cork tiles our kitchen floor is concrete. The inner glass is fine but all I have left of the door now is 2 brown metal posts with the white handle attached and some of the white glass glued(?) to the posts. I have checked about 20 websites and can find only 2 which seem to have what I need. However, since one wants to charge me £145 and the other £164, I want to be sure to order the correct part. So, should I be ordering a door glass outer and if so, how does it attach to the 2 posts and the handle? Many thanks
