This is how the OEM ball joint housing looks like all cleaned up.  NOS ball joints have different cup variations and the cups look more round on the edges as can been seen on Bills pictures.  The only thing that DC could improve are the BJ cups to mimic at least Moog cups and elongate the stud as Bill mentioned.  Not sure if the OEM housings can be molded and reproduced to concours & thoroughbred.   I remember in 8th grade Metal class we would put a metal piece in a sand to make a mold, then pour hot liquid to make another casting.  Does anyone have blacksmith abilities to reproduce the casting at least or maybe it's unsafe to do as the Supplier used a special casting to make these BJ housings. 

The last picture is how a similar NORS shaft Hex cups could look like to an OEM shaft cups.

I doubt they would be manufactured using a casting technique for various reasons including it would be too slow a process. I'm not an expert but I'd say pressed using a die.
