Chrome Starter Motor Bracket for Prestolite Starter Big Twin 1966–1981 – Replaces OEM 31476-66

This chrome starter motor bracket is designed to mount a Prestolite electric starter motor on Harley-Davidson Big Twin models.

The bracket provides correct positioning and support for the starter motor, ensuring proper alignment with the starter housing and ring gear. A chrome finish offers a clean appearance while maintaining the original mounting layout used on factory installations.

Designed for Big Twin models from 1966 through 1981 using Prestolite-style electric starters, this bracket is intended for service replacements, restorations, or rider builds where the original bracket is damaged or missing.

This part replaces Harley-Davidson OEM 31476-66. At Boomers Bike Shop, we stock starting system hardware that fits correctly and belongs on real Big Twin motorcycles.
