Need to make my own

Last year, I bought myself a secondhand Hornby operating mail coach. But it did not come with the ramps or any of the other kit. Now, for most of that I can figure out appropriate measurements where needed just by using the coach itself as a reference. But the ramps are another story.

So, would someone who happens to have the ramps please be so kind as to measure them for me? I need to know the total length of the ramp, the length and height (minus the spring) of the sprung portion, and how high the sprung portion sits.
The darndest thing is that someone actually did measure them for me last year, but I've lost my notes of the measurements and the eBay message with the measurements and ruler photos is gone because apparently eBay only retains messages for so long unless you use the archiving feature.

EDIT: Oops. posted this in the wrong place. Managed to scroll past the manufacturer-specific section somehow (despite specifically looking for it and wondering why I couldn't seem to see it).
