Hi Guys, Thanks to all who responded with help & information.I did finally get the right lower ball joints for my 57 Desoto from NAPA. All the books & computers were wrong.I now have the correct numbers if anyone needs them. We ordered a bunch in till we matched one up. As for the ones on e-bay I think they may be for the Desoto Firesweep which was a dodge with desoto front clip & tail lights as the correct moog part numbers are K713 & K714. But are no longer avaiable. Thanks Mike "57" Desoto |
