Need secondary coolant pump!

[Calvin Krug]

Help!  I was driving my '89 200 to work today, when the low coolant 
warning went off.  Luckily I had only a couple of blocks more to go, 
because when I arrived and opened the hood, I found that the electric 
water pump mounted high and to the left of the engine had cracked 
where one of the hoses connects to it. at least it's easy to get to. 
My local "Audi dealer" (and I use that term loosely, since they have 
NEVER had anything in stock that I needed) wants $195 for this thing, 
and of course wouls have to order it.  Anyone know of a good source 
for one of these, or even better, have a used one sitting around? 
The part number is 034-965-561-C.  Thanks.
