Harland sharp roller rockers - measure pushrod length

I am installing Harland sharp roller rockers on my set of trickflow 240 heads. I am trying to get a measurement for the pushrods.
I am not sure where the exposed threads for the adjuster are supposed to be counted from since there is a recess. Is it from the area where the threads exit the recessed area of the rocker or when looking across the bottom of the anodized area?

An answer to the original question........From the Harland Sharp website..............

"Pushrod length adjuster should not exceed more than two threads out of the bottom of the rocker arm."

I would expect this to mean from "where the threads exit the recessed area". Because that is the last place the adjuster screw is being supported by the rocker body. I would also interpret this to mean that no more than two threads should be showing after the preload or lash has been set.

Now, it's up to you to determine how and if this will work in your application.
