Jo, and anyone else who is interested, I dragged the driver side axle assembly out and put a tape measure to it.
Fully extended the axle assembly is 42.5 inches long.
Fully compressed the axle assembly is 41 inches long.
To be fully accurate, both lengths are probably an eighth-inch, or less, short. So add a short eighth-inch to the above dimensions to get the exact lengths.
Hope that helps.
