Thanks for the tip, but I cant get it to work at all as "disassembled" anymore, thats whats weird...
I have had a few problems with bolts that broke when tightening things up. Maybe because of too crappy quality in the bolts and nuts. I have tried two variants, but both break sometimes when tightening using a socket.
Since they broke on me, I have tightened more carefully and maybe i don't get enough pressure...
I have noticed that too little pressure immediately gives 2ROL (overheating).
Maybe I need to find better quality bolts, but then again as someone mentioned; it's not an engine top we are trying to assemble.
Still stuck though

If you are breaking bolts I would make sure you drill out your hole with a bigger bit. The H/S should easily slip all the way down. If the veins on the lower H/S is causing problems you can clip the large portion all the way around the nut (where you can easily slip on the socket) and file it down to the base.
