If you are fitting them to a Datsun B110, you will need:

* File the strut mounting holes (in the strut towers) out very slightly as the T3 tops use M12 studs and the 1200 uses M8 studs
* Use the B310 knuckle arms as B110 knuckle arms won't bolt to the large struts
* Use the B310 LCA and balljoint so it will fit the struts (B310 LCA is exactly the same as a 1200 LCA except for the balljoint and Tension Rod). See SAP for more details
* Be sure to get a wheel alignment after the parts are swapped
