Default Hydraulic engine mounts compression

I ordered a PU engine mounts as a replacement of my old leaky hydraulic engine mounts.
What is surprising for me is that the hydraulic engine mount height is 10.4cm while the PU mount is 86mm only.
That is almost 2cm difference.
The only thing I can think of is that the hydraulic mount will collapse a bit when the engine weight is pressing it down...but can it make those 2cm's?

Knowing where you ordered those from you most likely have to add spacers to make them work

Any experience with these classicswede?

Actually I think that the theory with the pneumatic mounts compressing under engine load is not valid.

The reason why I think so: there are these steel wires going around the mount, securing the top part of the mount to the bottom of the mount even if the mount has already degraded completely.

I remember how loose those wires were when the engine was still in the car. And now those wires are almost as loose as before. There is no way that the mount extended it's length by 18mm...

Ok, after some more checks it really seems that the PU mounts height is correct...weird to me but confirmed from several independent suppliers.
