Purchasing separate fittings for revell vii c

[reddevil]

Would it be possible to purchase some fittings for the REVELL VII C without buying the complete fittings kit? I mean: What I need are propellers and shafts, four 1/8" drive coupling sockets, a pair of dog bones, and some 1/8" ID brass tubing for stern tubes.
The important thing: How to pay, and how much (shipping incluided).

Regards from Madrid.
