Need help! Slipper clutch install

[So Cal SM450R rider]

Ok, so I finally get my slipper clutch that has been on back order since Dec. Its an Adige/Adler HU-52 for my 08 SMR 450. I follow the directions and even look at the install video from the website. I take out the old clutch pack and put in the new one. Everything is good until I put the original pusher back in followed by the pressure plate. The new pressure plate has a bearing in it which will not fit over the front of the pusher shaft. I think I might have the wrong pressure plate, (God I hope not) but I'm not sure. Not only that but there is a large black concave & grooved washer that came with everything and there is no mention of it in the directions. I don't know where it is suppose to go. Here are some pics of the pressure plate, 9 washers for the variable spring tention, the stock pusher,(which has its own washer between 2 flat washers) and the black washer. Someone please help me!!!

I know on mine the concave washer replaces the washer that has the tabs that are bent up to lock the nut in place. But I have a Honda and STM. It looks like to me that the pusher end (forgot the name) fits over the rod and then the pressure plate over the pusher end. No? does the pusher end that has the stacked washers not fit in the bearing of the pressure plate? Sorry not more help.

Exactly, the pusher end does not fit through the bearing that was in the pressure plate. Plus the pusher already has a flat bearing. It should only be one or the other not 2 different bearings for the same purpose. As you can see in these new pics, I took the bearing out of the pressure plate and the stock washer and bearing from the pusher fits in the recess, but the pusher plate is slightly too big to fit in the recess on the back of the pressure plate. Thanks for the info on the concave washer though. I wish there were a U.S. rep that was available for stuff like this.
