Will the half shafts off of a 1975 280z fit on my 1970 240? I can have them for free, so I want to know if they will fit.

The half shafts should fit if the 280Z has an R180 differential. If it has an R200, I doubt that the swap will work.

Length wise they should be the same . It depends on the U joints . Look at them and if they look the same as yours . there is a change that was made but I am not sure if it was in '75 or '76 . I have a R-200 in my '73 240 and am using the same 240 half shafts . Gary

I have CV's from a 280ZX on my R-200 diff that is in my 70' 240Z. There are lots of combinations but you just have to do a little measuring before you rip into it.

The R200 needs one side to be shorter than the other (if I remember correctly) so do your measuring and take the free parts either way. just don't tear yours out till ya know they'll fit.

Good luck,

Dave.
