Two pieces for each side means they're from a sedan.

That diagram SlowDB7 posted shows the main differences in the tails. '94-'97 USDM and JDM are essentially the same except for the lack of reflectors on the side of the JDM tails. That picture still has the reflectors on the side. See the things I circled here?



Those aren't on JDM '94-'97 tails.

If you look at '98-'01 tails the area around the lights themselves on the lenses is the same shade of red as the brake lights rather than darker like the '94-'97 lights. The JDM '98-'01 have the same lighter borders, no side reflectors, and amber turn signals.
