Depends on what you have that needs fixing. If it is part of an autopilot system that uses an electric gyro, the first choice is the manufacturer. For example, Century for a Century I AP Turn Coordinator. In the case of a system that uses an air gyro having a heading bug, i.e. Century II, you have more options. There have been reports that Century no longer wants to support their legacy products; so you may have to use that alternative sources.
Air gyro repairs, i.e. Mitchell heading indicator, Mitchell artificial horizon:
My #1 recommendation for air-driven gyros is NuTek Instruments; their link is on BAC:

Outstanding shop that does outstanding work, at a fair price; and been around for many years with a great reputation. Also very helpful with recommending similar shops for work they are not certified to do. Overhauling an older air gyro is generally far less expensive than a new gyro. If still repairable, the old Mitchells are far more robust than the later replacements, and are well worth overhauling. NuTek cannot work on electric gyros.
Electric gyro repairs, i.e. Turn Coordinators:
Try Century if it is a Century I AutoPilot (AP) TC:

Note that you can also obtain a free Owner’s Manual for a Century AP, from Century.
If no luck, try CE Avionics in Sanford, FL:

Another possibility is Mid-Atlantic Instruments, but I don’t have contact info for them.
Berkshire Instruments has been recommended; they are in Colorado. Here is their link:
