Not wanting to loose anyone a sale but it's not as simple as chucking in a single poly-mount.
Vibration will be amplified at that point alone, as I'm guessing the mounts either end (torque arm and Engine mounts) will be rubber on yours, Martyn ?
I'd be half interested in the clutch as a spare (I have a RAM with ally flywheel) - I'll keep an eye on it . . . do you mind if I ask the reserve ?
I would've bitten your hand off 3 years ago !!!
