There are used ones on ebay right now. Use nova for the search, I saw a set on there yesterday.

Chevy 11 Only in Mount Washington Kentucky has them at $84.95 per side, #69171 left and #69172 right. Their phone # is 502-239-8487, I have bought parts from them, ask them to ship using the U.S Postal system to avoid broker fees.

I just can't let this post go without stating the obvious.  When you post a request  for information or parts how about telling us the year, make and model of the car.
It isn't that we couldn't have taken a guess but why do we need to.  You might have gotten more than one response and could have even found a used set for half the price but the fact is some guys won't even bother asking if you don't bother posting the information.
