Sounds good

The Datsun 1200 struts are already coilovers with a Ford 4.5 inch pattern (same as Mustang/Falcon). If you are thinking of 5-lug wheels, maybe you can use the Ford 5-on-4.5 discs which bolt onto some Nissan struts (see Brake Swaps#Ford), although many Nissans incuding S14 240SX uses the same bolt pattern

Using the 1200 struts mean lighter weight=faster performance. You can also convert them to adjustable spring height or convert them to small-diameter coils (useful if you will be fitting extra-wide front wheels)
