I've got a set of motor mounts I modified for the swap of an OM617 engine into a 107 that would be perfect for you. I originally used a Shore A 75 urethane that was way, way too stiff. It functioned pretty much like a solid mount. I also filled the transmission mount and while the vibration was not oppressive, it went away completely when I went back to the stock transmission mount. I've since re-done the mounts with a far softer Shore A 30 urethane which is perfect for a swap like mine that needs to be vibration-free yet cannot tolerate motor mounts collapsing due to limited clearance.
The Shore A 75 urethane would be perfect for your application.
It's very simple to do and the effect would give you what you are looking for. I'd sell you mine, but the shipping would be prohibitive to the UK.
Here are the mounts immediately after pouring and the finished product.
If you can get them over there, I'd recommend Meyle for this mod. Notice how the flashing on the mount makes for a perfect containment vessel for pouring the urethane without any modification as compared to Febi or other brands which are difficult to seal up.
