NOTES:

Fitment is based on alternator type, not engine size.

Designed for vehicles originally equipped with a CS130-style alternator (typically mid-1980s to early-1990s GM applications).
Compatible with serpentine belt systems only.
Fitment is dependent on mounting bracket configuration, wiring connection, and pulley alignment.
May require wiring modification or conversion depending on application.
Not all listed engines are a direct bolt-on — verify alternator type and mounting style before purchase.
