The official advertising labelled them as buy what you like from off the shelf bolt on kits. Included arch kits, wheels,twin 40's 45's, Grp 4 Air Filter and various other Grp 4 equipment including suspension etc. If I remember right the brochure said that you bought what you liked and made it your choice. That would tend to suggest that none of them were actually made as x-pack more a car with after market parts, as we know capri, fiesta, granada and escort came with additional x-pack parts. I may well be wrong but I've never saw an actual complete car x-pack new price list from the many original Ford retail lists I've read in various magazines.
