AFAIK there's a difference in the width of the hub upright that goes in between the flanges on the shock (couple of mm, but enough for it to not fit the wide track hubs).
i think i have a set in the spares department out there too. the rears ones were ****ed though but front ones good off low mileage UK car. widetrack too.
Im sure the storage fees far out weigh the value at this stage ;p
