These aren't so easy to find. I've noticed folks around here using amateur cut pieces of plexiglass and such as substitutes. I can imagine how hard one is to find down there.
Try your luck here:
Car-Part.com--Used Auto Parts Market
Surely someone will ship internationally. One close to me is "Tony's Auto Parts" that has one for $100. Pretty sure Tony won't ship but $100 is a fair enough price around here. Some folks get $150.
Good luck!
