And additionally I got these from Tuomas from Finland from his E32 750: Shogun: Would these pics help?

I took some when I disassembled mine, if those are any help, please be free to use. Seat attachment bolt visible only when seat it up:

If you remove the motors (makes it a bit more easier) this is the last bolt to open. If you open it first, you can't get it out as seat frame is blocking it. Also first to be put back. (Seat front downwards in pic):
