To simplify the catalog listings of the above sockets, the manufactures round off the sizes to 1.750 or 1 3/4. Actual measurements are 1.78-1.80.
Great detail, Much appreciated.

I was leaning toward changing my upper control arms to later model but upon asking Cass at Dr. Diff when they may be back in stock, he said that due to quality control problems, he won't stock them again until someone else starts making them. That makes me a bit nervous about getting any repops for now so I need to find a socket.
