I try to match my old bead to your part and so I can make an order. The height and width of my old one is about 1/2". In terms of the shape, my old one is very close to your 55-156. The height of the 55-156 is 3/4". Also the side flange of my order one is a little bit closer to the top.
A picture has been attached for your reference.
Thank you and best regards,
Xiaoqing.
