Speedometer Help

[krwaggie08]

The back of the speedometer where the cable connects is busted. I am looking for a replacement, but can't seem to locate one like this. It is pretty simple, no electrical connections, just a place to screw in the cable and insert a bulb.

The gauge is a Stewart Warner with the number 835633 on the face. Anyone know where I can find a replacement? I have searched the web but can't find anything anywhere. The PO restored everything in 1998, so I am thinking the gauge is obsolete...

Pictures attached.

You don't say what diameter, the one in the link below is 3-3/8 and looks the same just a different part number.
