Interesting.  Is that because the inside of the nut that holds strut in place and is a different size than stock? 

Yes.  That's why I mentioned the gland nut.  Even the 240Z strut tube is smaller than 280Z, so even though the shock fits, the gland nut won't.  As I understand things.

Tokico had distributor problems a few years ago and never really recovered.  I think that they might have changed ownership and things got very screwed up.

Cool. Learned something new. I don't mess with struts very often. I've taken them, apart on parts cars, but on the cars I've had I have not needed to replace. 

I will need the info for this car.
