umbau beifahrer sitze nach fahrer sitze ?

I try to explain it in english:
I bought a very good teilleder 16v sitz with good lether and fabric!
The back part with the side wheel to controle the angle of the seat. How can i convert that from rightside to leftside ?
i alrady tryed this:
I drilled out the 3 popnails, removed the unit. But then i cant figure out how to remove the last parts......
In my mind i saw a topic on some board where they did this to ?
The seat part i already changed from right side to the left side:)
Sorry for my bad english...
