'89 100 Rear calipers

[vilr@jupiter.sun.csd.unb.ca (Pierre Villiard)]

Hi Audians,
    Congratulations to all for one of the best lists I've subscribed to.
    Could someone please tell me where to find left + right rear calipers
for an '89 100 at a more reasonable price than what dealers want? Given
that I'm in New Brunswick, Canada, it's of course expected that they may
have to be ordered from the US or from another province.
    Thanks.
