You don't "get" them....you just make a simple .txt file.
LIKE THIS
name = Component name
preview = Component_preview.bmp (and make sure you have a pic in the folder)
dir = (folder where you put the .gmf and preview pic)
model = component name.gmf
type = extras (weapons....whatev)
base = Component (Weapons....whatev)
styles = Default
description = reskinned component
damagesounds = sounds\chorus_metal_tink.wav
attachsound = sounds\cmp_generic.wav
Mass =200
hitpoints = 9700
concussion = 8
fracture =6
piercing = 1.3
standard = 1
Hidden = 0
You can also add this....
styles = Component, componentgreen.txt, Green Component, Componentblue.txt, Blue Component, Componentred.txt, Red Component
And put the green, blue and red .txt in the styles folder
Then put it in the Components folder and make sure you have the .gmf and preview and such
