Yes, but they are connected in the mazda via the ladder beam, to keep the diff from twisting. the rubber connections are where the diff/box/engine structure join the subframes, so they are isolated from the main loads on the body. Remember the gearbox mount on the mazda is not rubber, its stiff. I was thinking by using the transmission tunnel as the ladder beam (maybe with a few additional diagonals) and solid mount the drivetrain to the tunnel, it MAY act as the original ladder beam in the mazda. rubber mounting as the original car will give a little flexability.
for instance, if you hit a bump on the road with the rear left wheel, the rear left of the car would twist slightly. if the diff was solid mounted instread of bushes then this would twist the diff arm with the framework, stressing the diff arm.
On another note, can I ask why you revised the handbrake plate at the back of the tunnel a few times? im setting mine up now, and I cant see any problems. it cant be that easy can it?
