Centerline went out of business a few years ago and the brand was bought by someone else. However they hadn't made the Autodrag style of a lot of years.
I have a set of 120 4 bolt Autodrags (2 x 3.5, 2 x 5 & 2 x 7) that I bought via eBay and the Samba in the USA. Set up an account with myus.com and you can shop online in the US and have them shipped to Florida. Once you have collected your set there simple click on ship. Mine came Fedex and took 3 days door to door! Even with shipping and duty they were cheaper than I would ever have got in UK / EU.
