I order parts about once a week for the restoration of my Grumman AA-1A. Service and prompt delivery are always above expectation. I don't know what I would do without Military Fasteners and that's no joke! Thanks for your great work!

I called the customer service line just before Air Venture at Oshkosh to find out if they would have the parts I needed at their booth. The service rep on the phone was very helpful and was able to check the inventory that was taken to Oshkosh.I was told that the parts would not be available but could be shipped from the warehouse without delay. I ordered a full set of intake seals for a Continental 085 on the spot and they arrived in a few days. I am very happy with the service provided, and will be ordering more parts soon! Thank you Larry
