The base has 31202 embossed onto it and 5436 printed with black ink.
Each wheel has 31204 embossed on it.
The metal axles have no visible part numbers.
What is the part number for the chassis/base to be used in LDraw?
What is the assembly number to be used in LDRaw?
Shall the c01... follow the same logic as in BrickLink?
What u number can I use for the metal axles and which color would I make it?
Is there any special way to mark these parts as members of assemblies/shortcuts so that they do not get used outside any assembly?
The base is 31202.
This assy is 76139

The axle is 71956. Use colour 494, "Electric_Contact_Alloy" (in the wheel+axle assy)
The wheel+axle assy would be 71956c01
Use a ~ in the descriptions of all parts except the full assy 76139
