extended upper for working with bigger lens

hi

problem i bought the NN4 to work with 16/35 f4 nikon and 24/70 F2;8 and it did'nt work

i found just at 24 with the 16x35 a good nodal point but at 16 we need just 1 or 2 cm more depht for nodal point .

my idea and question do you think it could work if i add a manfrotto quick release 357 on th upper to get more back my camera .

thank's

how many cm the t plate give on horizontal

thank's everybdy

i want to know how many cm backward to the original plate the T plate give me is that correct

(They may also be used as an extension (up to 22mm) to the upper or lower rails of Nodal Ninja’s.)

how the QR can give me because if i understant they use it verticaly and for me it' s horizontaly i need to move my camera backward

sorry if i m not so clear
