Hi David,
I think you will find that the engine and ecu are the same as the Fiesta RS 1800 of the the year you quote.I have a 1994 silver top and have bought gaskets relating to the RS1800 and fitted ok.
Morgan had these engines stamped up with a number relating to there build not a known ford engine identification.
Hope this is of help
David
