Recommendations for Instrument Repair?

I need to have a ground plug fixed on my oil pressure gauge and would like to do this locally if possible. Do any of you midwest guys know of someone here that can do this kind of work? The plastic ground plug with the male spade connector is loose on the back of the gauge and seems to be the cause of erroneous indications. The gauges were rebuilt by No. Hollywood Speedo a couple of years ago, so they are in great shape. Any suggestions locally so I don't have to send it back to CA? Thanks.

Anyone...?

Scott,
If it just a connection that is poor you shoul dbe able to repair yourself. If you need a new part you may want to try looking at the online Stoddard's catalog.

Thanks Phil. I am figuring that I will be able to do the repair myself, but was looking for a back up in case I needed one. I'll pull it out this weekend and see what it presents.
