To clarify that:
I measured as close to those points as I could.
But, if this is for a piece of gear that is expensive and would become worthless if it is made the wrong size, I would strongly reccomend that you call Eibach and tell them what you plan on buying, what you need the measurments for, so that they can give you an exact length.
I don't want you to quote some guy(me) off the internet to get a number that is very important to an operation that could cost you $$$$.
Just my $0.02
