Here is a new old stock factory original 1957 Buick RH (passenger side) lower ball joint. The ball joint is complete with mounting hardware; see photos. This is a factory original. Notice the casting number, not a refurbished, no core charge, you can sell your cores to Rare Parts for $200.00. Rare parts part number is 10290 and Sturdy 11264. I have 2 of these and 2 of the driver's side on another Craigslist ad.
-----It can be picked up at
