After searching around about modding this qanba q4 stick with a LS-56-01 I dont understand if and what type of mounting plate I will need?

Some say I dont need any mounting plate, just a straight swap, other posts say, I need a S shaped mountingplate, like the original is.
And last post i found was about the MS plate from akihabarashop.. The MS plate is just plain straight.. not S shaped as the original? :S
anyone who could shed some light on this? Do I really need any plate? and if I do, wich one?
Please check the akihabarashops mountingplates for seimitsu, since I will be ordering from there, or show me a picture so I can check myself.
Thanks in advance!
