Hard to tell from the pics (nothing to scale it against) but I think we are taking about the "bumper" that goes on the diff end of the driveline. When it is not broken up, it looks like a mushroom or "T" plug. In other words, that washer looking thing is supposed to be one piece with the plug looking thing.... the plug part then fits in the hole in the diff end of the driveline, and the washer part forms a cushion between the end of the driveshaft & the bottom of the socket it fits into. When I did my swap & pulled the driveline, mine looked just like that. The Yami dealer shows that piece on the parts diagram, but it had no number or name, so he said he couldn't order one for me... even called the factory, and they said I needed to order the whole diff or driveline assembly (they weren't sure which) to get it. Finally ended up machining my own from a polyurethane suspension bushing. Maybe Yami has their shit together now.... good luck.
