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!

Keep on keepin' on! Living in Nova Scotia puts me in somewhat of an aviation backwater where getting aviation hardware can be a bit of a nightmare. Military Fasteners resolves most of the angst and dealing with the friendly and helpful staff I find there resolves the rest.

Nice online shop, with very fast operation and high quality service. A bit expensive and without quantity discounts but worth the money in general.
