The adapter is good quality, but I had a little issue. The issue was that the center bore was just bit small to fit on the 82 Corvette suspension I was working on I looked it up and while the factor C3 hub is 70.6, most the internet uses the 70.3 the C4 and later used. I didn't really check that before I ordered, so my fault. I just sanded a 0.3 mm off the inside, good enough for may use.
