Not obvious from this side, but the back of the bulkhead panel is doubled with 3mm alloy plate - my 2a started life as a FFR and it has a large number of holes in it, so changing from a soft top to a cab ute meant I had to block the holes somehow to keep the water and the dust out. This means that it is far more strongly reinforced than the 10cm square 1.5mm plate spot welded in place on the S3 I pinched the bits (and the cab and doors) from.
