As above, RWD Saff, clutch was recently replaced (as in last week) and it's starting making a heavy vibrating noise below 3000rpm.

It does it only when in gear or pulling away etc... i.e. not on the spot and revving.

It sounds just like the when the doughnut bush on the prop went on my old BMW E36, but I am told Cossies dont have the same set up?

What is it most likely to be?
Hopefully just the exhaust rattling but thinking ahead.

Cheers
