my small t has the following big t parts fitted from the factory=

big mirrors
no airbag
wipac immobiliser (as opposed to the ford red key)
big turbo badges on bootlid

this is because mine is a very early small t and was built for the export market, some other early small t cars had big mirrors and big t badges aswell, but I have yet to see a factory small t with no airbag!
