I needed some long AN6 bolts for my Swift DB3 restoration project (the long bolt that support the lower eyes of the rear shocks). These were not available here in the UK and various suppliers elsewhere were showing them as on back order.
B&B Aircraft Supplies, Inc, of Osawatomie, KS not only had them in stock but their prices were excellent. They took my order and were happy to post to the UK, with the bolts arriving safely this morning in just over a week.
The bolts are fully marked, US-manufacture. I'm happy to recommend them for great service!
