Camaro Idler arm and pitman arm castle nut
 

does anyone know the torque specs for the castle nut that connects the idler arm and pitman arm to the centerlink on a 68 camaro?
thanks

I was looking in the factory assembly manual, the only spec I see for castle nuts are the tie rod ends, aren't they the same size/thread as the centerlink?
Strange there's no callout on the centerlink nuts,that's why i'm thinking since it's the same castle nut, the tq. is the same as the tie rods.

30~40 lbs-ft (50 lbs-ft max to line up the hole for cotter pin)
