I need to know what the length is from top of upper cage to the middle pivot point on the side bearing/trunnion. Not sure if on the above mentioned scope it is the top of mirror box or not. I wanted to know to see if scope will fit in my observatory. If i decide to get one. Still undecided at this point. Just trying to plan ahead and explore all my options for a big scope.

Just measured mine. 62.5 inches. It may be a very little more or less depending on whether the truss poles have been shortened or not. Also yes, the pivot point is the centre top edge of the mirror box - that is where the centre of the altitude encoder sits if one is fitted. Total assembled height of mine from floor to top of UTA is 83.25 inches.

I believe Obsession's web site has these type of specs listed.
