where to get castle nuts?

I am bagging a 87 c10 at a friends shop and he swept up 1 upper and 1 lower balljoint castle nut.. does anyone know of a place other then a junkyard to get just the castle nuts?

oreillys sell them or autozone. I know cause i work there, where do you live? In lancaster TX?

no, lancaster, pa

well if you have an oreillys they should have them, or should be able to get them for you. Autozone probally has them too

just called AZ.. they told me no.

i just called an oreillys back in oklahoma where i know they have them. They said they just have a universal one, they cant tell me what it fits.

can you get me a part number for one that you KNOW fits the upper balljoint of a fullsize and 1 for the lower balljoint?
