Source for right rear tie rod 83 Ur-q?

[David Ritter <dritter@mich.com>]

I am looking for a #857 501 499A for the 83 Ur-q. I have tried the
usual, Rod at TPC, Blau, my local independent, and have come up
empty. Rod said that November sometime would be a good time to look
for one. Anyone sitting on one of these? Audi dealer price is a bit
too high on these, of course. Our weather is turning toward the frozen 
stuff, and with my present alignment, the Ur-q will be a bit scary.

Thanks,

David
