Nope, the NH3 bits to fit the NF5 (RS) gears to the NSR cases are in the normal SS/SP mc21 HRC manual.

I could tell you where the PDF of it is but then I'd have to kill you.

TBF it's also in the members section here, page 22 and 23.

And as this is skirting on the edge of what should be discussed in the open Forum I'd ask to to take further discussion inside
