Anyone happen to know the thread pitch of the UPPER shock nut/stud..Bilstein Hotchkis

[uraceulose]

68 Camaro, rear shock. Need another nut (non nyloc type) for the left rear upper shock stud/nut. They are the Hotchkis valved Bilsteins.

Will check myself tonight when I get home but just thought I'd post up and ask first.

Thank you,

Donnie
