Also, is there a lock washer on the nut side? I am so ticked at myself for not taking a boat load of pictures of my late father in-laws lemans. I used it for parts. stripped it & scrapped the body & frame. Was stupid crazy rusty, but was bought new by him & never messed with. I so badly want to go back in time & just put in away complete. so many details like this that I could have used as a manual. not saying everything is the same on a lemans, but both that car & my GTO were built in pontiac MI about 3 month apart. I probably only have 4 or 5 pictures of it.
