Ah, that japanese guy has updated his webpage it seems? - he does some funky stuff to his ZR4 - he made his own angel eye headlights, whacked on a bumper from a Mazda Capella/626 Wagon/Ford Telstar and a few other interesting things.
misterfixits scans show a VR4 touring car with those mirrors.
Doesn't look like it would be too hard to rangi them up - I mean 'custom make some mirrors from off the shelf parts' /ubbthreads/images/graemlins/laugh.gif
