72 dart pivot shaft nut size?

[Ryansrt]

Hi I have a 72 Dodge Dart I ressurected from the dead and it's missing the nuts to the pivot shaft on the lower control arms. Does anyone know the thread size so I can just go buy the nuts?

5/8 x 18
Self locking nuts, and don't forget the thick washers, too.

Thank you I've been looking everywhere for this answer!!!

In a earlier thread, the member had purchased aftermarket replacement pivot shafts. Those were packaged with some unknown grade of off the shelf nut. The threads stripped before achieving the req'd torque. We can't know for sure if the nut, or the shaft, or a combination of both was to blame. anyway... High grade nuts in that size probably wont be found just anywhere. Good luck
