it sounds like a shell from the '89 run that ford did of new shells.. they were avaliable in lhd or rhd, and with or without sunroofs, ie 4 different versions, and they were given 909 part numbers. I've got a scan of the original advert somewere if anyones interested..

EDIT...

9093550 rhd sunroof
9093552 rhd non-sunroof (motorsport)
9093553 lhd sunroof
9093551 lhd non-sunroof (motorsport)
