[928uk] Engine mounts

[Richard Armstrong]

Dear all
'91 S4
My engine mounts are shot  -engine as solid as a rock, vibes at 2000rpm 
and at 100mph in 4th etc.
The Shermans seem to have a source over the pond - some Ford truck 
mounts I seem to remember. Do we have anything equivalent over here?
Presumably the only other source is OPC, or do Euro car parts do them?
The job looks ok as I have access to a pit/lift, but any words of wisdom 
would be gratefully received!
