Product Description
M30 x 1.0 LH Thread MainShaft Nut For Datsun & Nissan 4Speed F4W71B F4W71C 32354E9001
The only confirmed catalog fitments are:
DATSUN 720 Pickup Truck 05/1981-10/1982 F4W71B transmission
and
NISSAN D21 Hardbody Pickup Truck 1988-1989 F4W71C transmission
There may be other F4W71B vehicles that use this LH thread nut
But, unlike the 5-speeds, Nissan did not document when the change from RH threads to LH threads occurred
This nut is NOT interchangeable with the earlier (RH thread) part number 32354-E9000
Unfortunately the earlier RH thread nut is long long gone
