Giuliari Dual Seat

On my ‘64 LiS I have a Giuliari dual seat frame (stamped) and originally had the original 4 vertical parallel springs fitted. I’ve now purchased a new set of springs and the vertical ones are tapered. I can’t seem to figure out whether the taper is at the top or the bottom of the seat frame, also the link going across the frame doesn’t seem to fit symmetrically! Does anyone have picture they could post of how it should go? Or have I got the wrong springs? Can’t seem to find anything on the web! Can anyone help me please?
