looks sierra/granada to me not sierra cossy possibly granny take the horn button out there will be a code inside the steering wheel starting with an 8 or a 9 see what it is
its not that bad but escort bumpers would fail the front panel would fail, depending on how you wanted it to be registered as in new car then everything apart from the engine would need to be new
the only way to use it legally is iva
unless its a ford manufactured or ford approved shell
iva wouldnt be that easy but worth a go to see what they come up with
