Guys, I need to determine the size and thread pitch of two nuts/bolts for a 72 RX2. The first is the nut that connects the idler arm to the centerlink. The second is the steering gear box that connects the pitman arm. It's like a 22mm nut. Any help would be appreciated.

 

Somebody else might need this info so figure I'd share what I found out. The idler arm stud is 12mm x 1.5. The steering box stud is 18mm x 1.5.

If anyone can tell me where to source these hex nuts I'd be ever so greatful. I'd hate for the car to sit another 15 years because a single nut.

Thanks for the info. I'll give the a holla.
