It
would be better for parts availability if Nissan had
just continued tapping all the regulators for the
screw after late 69 but they didn't. To use a
non-tapped regulator on an earlier car you'd have to
have the handle mount portion drilled and tapped. To
use a tapped regulator with the later clip on handles
you'd have to cut a groove for the clip to engage in
the peg that protrudes for the handle to mount on. You
can of course use the "wrong" handle for your car.
Some of the parts are cheaper then the other version,
and people sometimes modify things to go that
route.

There
are two types of window lift mechanisms used on the
68-70. They differ by the method used to attach the
window handle. Up to late 69 model year production the
handle was held on by a screw in the center of the
handle. Late 69 production and all 70 cars used a clip
on handle. These two handles are pictured on the
HANDLES
section page. Since 30+ years have passed, it's common
to see the cars "rearranged", so check what you
have.
