Possible alternative cab air spring?

[tacosauce]

I was looking around and stumbled on this cab air spring for the front of a Scania truck. It looks like it might work with an airline extension and a couple holes drilled, but I can't find any specs on it.

Anyone have experience with these, or maybe your google-fu is strong?

Well this link shows a length of 280, I am guessing MM, or about 11”. But it doesn’t specify wether that is extended, retracted or nominal...

From the picture in this eBay listing, and I'm not saying it's correct, it appears that the 280mm is extended.
I can throw this into Fusion360 and extrapolate the height based on the known 12mm bottom thread if you want me to.

What also isn’t specified is wether this shock is rated to also provide a retracted and extended stop like the original combined shock/spring assembly does. You would have to look at the structure of the truck it is specced for to see if it uses some other structure to control the travel limits...
