70-76 speedometer

Looking for a good used speedometer gauge for my 75 dart.
Does not matter if it is 120 MPH or the later 100 MPH.
The gauge must function correctlly including the needle returning and resting at zero. If the needle does not return to zero they are junk and not repairable due to the plastic piece being broken holding the return spring.

Let me know what you have!
Thanks
