We are building the original Delco 10DN alternator as a higher output replacement alternator for the original factory units. You can keep your vehicle looking original and still run the extra accessories that you need. These units are available in 80, 100, or 120 amp varieties in natural or chrome finishes. They will mount and hookup with the original factory wiring and will be compatible with the stock voltage regulator. Need more amperage than this alternator can provide?
