there are some differents between A 81 to 82 280zx distributor shaft,
from 82 to 83 the distributor shaft in the 280zxt had A torx like setup
with thes lot in it , verse the 81 And down in yr had the shaft like the
regular regular z distributors that had only A lot in the shaft,
so make it is not the later distributor with the torx like input,
or else you will have to find A distributor shaft with this torx like input
on it, this was in the 280zxt that had the crank trigger dial right inside
the distributor its self, on the earlier model turbo cars the crank
trigger was on the outside by the crankshaft.
