Hi Guys in VKB

At first, the MKIV with MCGU I've got two weeks ago is superb!

I have question about dimensions for mounting stick base to plate. I've found two blueprints one DIY blueprint and VKBs official, but dimensions between two upper bolts are different. One is 65, second is 64.2, which one is correct for MkIV base?

Top pic is VKB official, the second one is made by someone else, so whatever is mentioned on the first one should apply.
