What part number should I use?

[Magnus Forsberg]

I want to create a new assembly for a complete micro-motor. LEGO Service pack 5119

Code:

1 16 0 46 0 1 0 0 0 1 0 0 0 1 2985.dat
1 16 0 26 -20 1 0 0 0 0 -1 0 1 0 2986c01.dat
1 16 0 10 0 1 0 0 0 1 0 0 0 1 2984.dat
1 7 0 26 -20 1 0 0 0 0 -1 0 1 0 2983.dat

What part number should I use, and how do I colour it?
There's already an existing shortcut 70823 in the library, hardcoded in red , so I think it would be wrong to create 70823c01 as an uncoloured shortcut.
