See rear wing pics of a rev 2 and rev 3+ and you will see the rev 2 spoiler assembly also goes along the rear wing.

Not all rev 3 aerials are the same.

Some have wiring differences even if they have the same connector.

If you need to replace your aerial go to your local car audio centre and get a generic aerial.

They will also replace the connectors for a modern standard one so less hassle if you ever had to replace it again.
