YES, and you get to that cam from the TOP photo in Mr Miata's post.

His LOWER photo shows you where the hex bolt is that locks/unlocks the rear bow.



Try watching my video FROM BEGINNING TO END, and listen to what I am saying the entire time and you will understand.
Putting the top up and down manually is easy, very easy. Every owner should understand and practice it, should make sure they have the top tool and a hex key OR the new top tool with built in hex key - and be ready and able to use it in an emergency.



This means storing the tools in the glove box or console, NOT the trunk where you can't get to them when you need them.
