Isn't the dog bone the rear mount?
If this is the same as the Golfs, it is a piece of cake, just remove the two 13mm headed bolts that hold it to the subframe behind the engine, and then the 2 bolts that bolt it to the Gearbox. you can support the whole assembly, but there are 2 other mounts holding it all together.
Then get the whole thing in a vice and change the mount, i used some Loctite on the bolts to stop them vibrating loose, I had a Powerflex one on my car, but preferred the OEM one, as the PF one vibrated too much really.
The actual rubber is in 2 parts, you can use 1/2 the OEM one and 1/2 Powerflex to give somewhere in between.
