A couple of parts I'm after.

[Gouki]

Hi guys, I'm after a few pieces for some non-G1 'formers I have to make them complete again. Namely:

Animated Leader Megatron Missile
Cybertron Excellion Gun/Missile
MP-02 Ultra Magnus Megatron gun

I'm hoping someone can help, or at least point me in the right direction, since I hate having non-complete figures, but it seems the only parts that are easy to find are G1 parts (which makes sense really). The MP-02 doesn't bother me as much, but the first two? Any help would be muchly appreciated!

Thanks.
