My old Nissan catalogs show this:

Ball Joints
B110 - PN 40160-H1000
B210 - PN 40160-H1000 (1975 catalog)
B310 - PN 40160-H7400

I've got some new B110 balljoints at home as spares for my white 1200 sedan. They are new in the box. I'll look at the part numbers on the box when I get home.

I'm not 100% sure that they fit, but I expect that they do.

Cheers,
Chris.

I bought some new front lower ball joints for my ute but they don't fit. All the parts books show this part number BJ92(or similar).
They are very close but the spacing on the mounting bolt holes is different.
Perhaps these are for a 120y or sedan. I have had the correct ones fitted now not sure what the part number was but now i'm stuck with 2 brand new ball joints with no idea what they do fit. They are the good ones made in Japan.
Can anyone help as to what the difference is and what they will fit. I will need to sell them as they cost $52.00 each!
Anyone need some.
