Where can i buy a temp gauge?

Can anyone tell me where I can get a replacement tamp gauge? I pulled out the cluster a while back and after putting it back together the gauge was not working. I've tried taking it out and checking all connections and even replaced the temp sensor and temp sending unit.....but no luck.
If i have to, i'll go to the dealer for the part but i'd rather find it online somewhere.

much appreciated
