I've measured my front struts - the rears I forgot I sold my spare pair so I'll measure the set on the car at the weekend.
I tried to make it as simple as possible so I measured from the upper mounting hole to the underside of the spring pan the flat section close to the strut body (there's a small hole there on my front struts don't know if that's standard) and from the top of the strut body down to the other side of the spring pan. I'm calling the dimensions A & B on the front struts and C & D on the rear.
Pics should make clear.
FRONT

REAR

So far
A = 172.5mm
B = 77.2mm
C = TBC
D = TBC
Note mine are rebuildable ones, dimensions B & D might be a little different on sealed units.
If others could oblige we should be able to put together a simple little chart
