Finding the drivetrain will be easy, as you can just buy a 1g for a parts car. That will probably be the most cost effective way. If the front end damage is only $400, it sounds like a great candidate to save. Body panels are relatively cheap if you can find them local. I haven't sold any from the car I parted out, so they can't be in high demand. The interior bits are cheap, but the driver A pillar and few others are getting hard to come by though.
As transparentdsm said, it really just depends if you want to put in the time and money. Owning or building are GVR4 is never a wise financial decision, you have to do it because you love these cars and are most likely saving one. Its too bad you are so far away, I have a good radiator support, rear window, and front clip from my parts car.
