273 adjustable rocker conundrum..

You've seen the adjusters on the crane rockers that I have and how far out they are... On these Factory ones I've taken up almost all of the adjustment within a couple threads so I should be able to booger them up kind of high so I get lots of thread in there before they start getting tight and not just boogering it up all the way through..
And about the Crane rockers.....what size are THOSE adjusters?
