I've got an Erebuni MazdaSpeed fiberglass wing clone here. It's a little scratched up (you should probably respray it) but solid, and has mounting hardware.
It's the last item I have left from my MX-3 (other than the shift knob). So sad. I still get the same feeling when I see an MX-3 on the street or pictures of one...
It's boxed up real nice and ready to go. $200 + shipping. Shipping is likely to be $150-200...

PM me. I can be flexible about shipping so if you find something cheap that's not too hard for me to do, we can do that. I live in Santa Cruz, CA, 95060. The box is ABOUT 60x19x19" and ABOUT 15lbs (I don't have a tape measure.. and you believe it??)
Cheers.
PM me.
