A lot of knowledge in a very short time!!!

First in response to length questions and I hope my measurements and terms are ok.

I measured the exposed portion of the stem only ( I couldn't find the Allen key to remove stem completely). The stem measured 70mm from top of the spacers to top of stem (exposed portion - not counting what is in head tube). Since only 70mm are showing shouldn't there be enough room to add a taller stem????

Stem then extends 140mm forward from top corner of stem to center of bars.

Head tube is 190mm from where forks join the head tube to the bottom of spacers

Top tube is 550mm measured from where top tube joins seat post to where top tube joins head tube.

Seat post is 145mm long from top of seat tube to top of seat post (again exposed portion only, not counting what is in tube)

Actual seat tube is 59cm measured from center bottom bracket to center top of seat tube (confirmed through Dave Moulton and on his registry as a 59cm.

Cranks are indeed 175mm.

Lastly all parts are Dura Ace expect stem which is 3TTT.

PS I am not ignoring the advice that says move on, just going down with a fight. Hoping to keep it but if I have to move it I will.
