Hi!
I need the complete height from a 31AC Hardtop from the bottom to the top of the hardtop. Has anyone this information and is able to give it to me?

Now I saw a few times some 31 ACs not with the 3 round windows in the aftcabin, they have elongate singlewindows. (see as example https://www.youtube.com/watch?v=6-f2Y7QCELI) Was it changed during the years or was it built in license or what else?
