Looking for a part # for a gauge cluster

Okay I have a gauge cluster out of a 2001 Cobra, and the problem is the temp gauge stopped working. So I'm trying to figure out where I can get the gauge rheostat that is on the cluster so I can fix it. So I'm looking for a part number. So if anyone can help me out that would be great.

I can get pictures of the part if that helps anyone out.

I already replaced the cluster, but again I'd like to fix the one that I took out. There are places out there that fix clusters, so the parts have to be available, just need to find them.
