fronts should be ok
you can check the rears for yourself - poke your head under the rear end, and have a look at where the shock is attached to the lower control arm. If the shock is mounted by a fork (u-shaped bracket) to the arm, then yes it will fit. If the mount is an eye (o-shaped bracket), then no it won't fit.
I don't have a 34, but by memory 33GTR do fit 34GTT
May want to check the heights though once on the car (but if they're height adjustable there shouldn't be any problem.
