    DD -
    Because it's castellated, you tighten it up until the cotter pin hole aligns. Can't really do that and get the exact torque for that size bolt.

    get what you are saying but how tight before you stick the pin in?
    i have a book from my old TR6. I use it for reference to get some idea. On that upper fulcrum they say 32 lb ft. I went to that and of course it was on a point of the nut. So I went on to the next flat which then turned out to be about 55 lb ft.
    guessing the strength of the shock levers will keep the bushing from too much pressure?
    Of course tightened with a 2” block in for spacing...

    maybe just remove the block and make sure it moves smoothly?

    DD - I just tighten it up to the last pin hole I can get without straining myself.

    If BMC thought it needed a torque value, they would have included it in the manual.
