Nf2 is definatly 2 holes.. for my nb #rotor style block, 2 of the 80 something holes are for mounting
Maybe he meant Nf3?...
Havinglooked at some pics of the NF4 DFI board, it looks like I will need to turn my block around, as it is rectangular and is longer in the directiontowards the PEG slot.. will be a pita though.. but gives me a reson to desolder itandmodify it for higher flow (which my loop NEEDS)..
