not sure if this helps....
when I did my tor... bars, the 2nd try I measured everything I could find. I ended up using small square, layed it on top of the spring plate (not the outer part that the eccentric moves) aligned it with the end of the spring plate, and moved the banana arm until it was 6 1/4 inches to the top.
(why was my pic smaller than Joe's?)
I found this reference the best place to fine tune getting the splines where I needed them as I put the spring plate covers on. This gave me 4" ride height with the eccentrics in the center.
But, I installed 29mm tor... bars. So not sure how close that'll put you on yours.
