Are you talking about the rubber guts of the mount or the steel that it sits in?
I had a 2 litre big valve MK1 years ago and only uprated the rear gearbox mounting and the front snubber. I had no troubles with the side mounts. This is where all the movement happens. If they are slack, then the side mounts get twisted continuously which doesnt do them any good.
There is a right and wrong way round to insert the side mounts if you take them out.
This is the kind of thing to find in the States I reckon. Possibly there is an uprated rubber one.
