Alternator was in stock, shipped same day, arrived quickly (even though I chose standard shipping during the height of the Christmas rush), packed well and at a good price. Well done, Military Fasteners, well done!

I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.
