I cut the threaded rod to get it down to the 120mm per drawing. Might need to be cut down more if it needs to be adjusted much shorter.
Drawing dimensions on where to locate the access panel looked to be way off center, compared to where the servo was located. So, I just layed the servo on top of the skin and centered the access panel around it
I retracted the servo fully, and marked the shaft with a piece of tape, then extended it fully. I marked the halfway point, then retracted it back to the midpoint. I wanted the servo to be located a close to nominal before any adjustments.
