PST lower control arm pivot shaft, dimpled bolt question.

I am also concerned about the status of the nut that is supplied by PST . However , I am sure that if you contact them you can get a reasonable answer . Did you try the OEM nut ? My sources say to torque the nut to 145 ft.lb. AFTER the car is on the ground with the weight of the car on the control arm to prevent binding . I think that the nut you show in the pics would screw up the torque value big time . Just my opinion .
