a few galant VR-4 specific questions

[s1ngletracker]

For the few of you that own galant VR-4s, I'd like to get some expert information (kinda hard to find this specific stuff about them on the net)

In general, my questions are around body and interior parts. Are they compatible between any 6th gen model galant? I realize that finding replacement stuff for a VR-4 might be hard and expensive.

specifically:
Can you use headlights from any plain old 6th gen galant? Can you use a hood from any 6th gen galant? How about grills, trim piece below grille/headlight? Bumper? How about seats and interior trim?

Thanks for any an all input!
