Dimension needed of AT 54mm plugged threaded forward closure...

[MarsLander]

If anyone has one of these, Aerotech 54FCPT...can you measure from the face with the threads to the face that is above the thread. Said another way, the vertical dimension from the largest polished face to the smallest polished face. Trying to progress a build...

Thanks!

I get 26.8-27.0mm, but I'm having to measure in two steps.
