Elusive final dimension

I'm trying to model a part (the front sight of a 1911 pistol) and I'm trying to fully constrain my initial sketch manually. I have one final dimension to place, but I can't seem to figure it out. I used the automatic dimension function to insert it, but I can't seem to duplicate it manually. If anyone could provide some insight about what I'm missing I'd really appreciate it. I've attached screenshots showing the sketch before and after the automatic dimension was inserted. It seems the same as the other two vertical dimensions I have in place. I'm using  the M1911 Redux drawings located at the following link:

Note, these drawings are not my intellectual property and are being used for personal reasons only.

Do not use automatic dimension tool.

Do not repeat dimensions (use equal =, colinear or other constraints).

 

Do use construction lines.


Attach ipt file rather than image.

 

My guess

no coincident midpoint to origin, missing horizontal constraint, missing equal constraints.
