Please Help - Measure strut tower distance

Hi,

Can someone please give me a lending hand in measuring the distance between the front struts as per the picture below (picture taken from forum user here, I hope they do not mind). Dimension should be center to center.
Help is greatly appreciated

Thank you


EDIT:
From which manual is this?
And are there such manuals for all Mitsubishi vehicles?
