It fixed my problem
My Mustang alternator died, causing my car to shut off. 1A Auto had the match and shipped it quickly arriving in a few days. It was a perfect fit and easy installation. Turned the key, car started as normal, problem solved, happy customer. Thank you guys once again for a good product at a very good price with excellent service.

Classic mustang alternator
The alternator was installed on my screaming yellow convertible 04 mustang. The item arrived on time and fit like the original. The mustang has only 60k miles. Installed innindefv20 minutes and it runs perfectly.

Ask a question to 1A Auto customers who purchased the product
My 2004 Mustang has the 3.9 engine, not the 3.8. Does this alternator also fit the 3.9 engine?
