If you look at the first pic of the thread (see below), you will see the front engine torque mount ('the egg') in two pieces (just in front of the right hand front tyre)
I replaced this while the front end was apart too.
I removed both shims from beneath the top chassis mount (these are visible still sitting on the top mount just under the Harmonic Balancer in front of the wheel too), and still had about 1mm of clearance on the new mount. The instructions say it should be a good fit (or words to that effect), neither stretched or compressed.
So I shimmed the lower mount using a washer and needed to be careful how I tightened the nut to prevent adding any twist to the mount (which has locating tabs).
Makes a difference to the smoothness of power delivery I must say. Good item to repair.
