North Kent.
It's the steel one, removed from mine, as I had the alloy one kicking around.
If yours has seized up like a stuck pig then this will help. I'll hang on to it for a couple of weeks then it's getting binned.

Just wondering what the difference is between the steel and alloy rear sub frames on a 147. EPer shows the alloy is only used on the GTA and Alfa Workshop mentions this gives a wider track. The transverse arm mounting bolts are different but other than that I'm assuming it would fit a non GTA 147 or would other parts of the rear suspension need changing also ?
