The wheels are the same for all three models of the 910 Bluebird, but differ in the center cap. Series one says Datsun & series three says Nissan. I can't be sure about series two, but i think that they say Nissan also.

The wheel nuts are unique to 810 & 910 range of mag wheels too. I bought a full set of new ones for my 200B SX wheels & I don't remember geting an awfull lot of change from $100. I wasn't able to get the nuts from aftermarket sources either.

These are good wheels, with a practical width for L series as well as A series powered cars, & if they come with a full set of nuts, they are probably a bargain.
