Boeing B747SP drawings

[Boeing_lover]

Hello,

I am currently looking for technical drawings on B747SP.

I need following type of drawings:

Fuselage and wing cross section drawings

Fuselage station drawings

Possibly aerodynamic loft 3 view drawings.

Engine pylon drawings for Rolls Royce engines "RB211-524C1's"


I am trying in these forums to get these as other forums doesn't seems to help much, I can't use freebie web drawings either. I would appreciate if someone can help out or least point me in right direction where I can find these.

Cheers,
Boeing_lover
