Upper Ball Joint nut size

[jetheft]

I purchased an un-finished Mk 3 and the nut for the upper ball joint is missing.

Do you guys know what size castle nut I need. My lower ball joint is larger, I have an extra lower.

Thanks
Joel

Joel,

We do not have the specs for the castle nut as it comes with the upper ball joint as an assembly. The upper ball joint is from a Chrysler New Yorker 79-82.
We carry them. They are sku# 14897 and they cost $20.

Thanks Brian!
