Stewart Warner ST 960 AA Tachometer: Modernized Restoration for Reliability

This Stewart Warner ST 960 AA tachometer had a completely failed movement. Our solution was to modernize its internal workings with a reliable AirCore movement and our custom circuit board, ensuring accurate and dependable performance while preserving its original look.

The Modernization Process:

• Full teardown (found new OEM chrome bezel)
• Original faulty movement removed
• Custom CAD-modeled adapter created for new movement
• Durable ASA plastic adapter built
• New AirCore movement and circuit board installed
• Cosmetics restored with fresh paint and silk-screened face
• Pointer repainted and polished
• New glass installed, bezel recrimped, connections labeled

The result is a vintage tachometer with the classic Stewart Warner aesthetic and a modern, reliable movement. Contact us for similar gauge upgrades!
