Ok, here we go:
Cobra, Corroded skin, normal spoiler and bumper, raider wings and tail. Colours for corroded skin not really aligned well.
Cobra, Medusa skin, normal tail and bumper, raider wings and spoiler. Normal skins don't really match raider kit.
Anaconda, Corroded skin, raider spoiler and bumper, normal wings and tail. Seems to work much better than cobra, possibly choice of corroded skin was better.
Anaconda, Expo skin, raider wings and tail, normal bumper and spoiler. Seems to work much better than cobra, possibly choice of corroded skin was better.
From what I see the skin matters most to fit with the ship kit. Mileage and taste may vary though.

Personally I don't feel they fit together, I tried different raider bits on the Conda Expo skin and didn't really like any of them. Dealers choice though
