Looking for used/non-working speedometer sensor
 

I'm looking for a used speedometer sensor that goes on the driver's side of the1989 and 1990 964 transmission right by the driveshaft on the plate covering the differential. Doesn't need to work as all I need it for is to plug the hole. If anyone has one laying around that would otherwise get tossed, I would much appreciate it. Will pay shipping, etc. Many thanks.
