My friend had this problem about 4/5yrs ago.
He went to local ford dealers who listed all the panels and priced them at about 1k (if my memory is correct)
He purchased the new motorsport shell and went back and ordered the parts only to get a phone call saying although listed they were not available (W***ers)
Ended up going to a scrappy for a escort mk5 top bulkhead and a sapphire 4x4 lower bulkhead.
Major work and would not recommend it to anyone.
