I've got a Club Sport V1 Base and to the centre of the shaft its 70mm from the base. I presume the 2 and 2.5 are the same case, it wouldn't make much sense wasting money retooling for things like that.
This should be everything you need. It's not the absolute height, it's in the layer of the front plate. Mine is angled on a wheelstand so I couldn't really measure the heights.
I added the 20° tilt due to the attachement adapter. I'm sure you can figure out the absolute heights from there
