American Classic used to be in Texas, but were bought out by Classicparts.com in Kansas, if you poke around on the site, you'll see they are on the same street.
They kept the user names and the URL, but if you check the parts numbers, they are the same for each part on both sites.
Also, as I recall when ClassicParts stopped being chevy duty, they weren't sued as they had a license from Chevy/GM to use the name for a long time, but GM informed them that they were going to stop licensing the chevy brand as much and get more control over it, so they had a heads up about needing to change it.
