Ok we need to look at your requirements first.
Must fit under (standard) Datsun 13inch wheels.
..You can only use the local 200B discs and calipers! These have long/skinny brake pads. Whereas the imported ones are more square, and use aluminium finned calipers that hit on the inside
of a 13' wheel. Some mags are ok though. I would more strongly recommend that you use the large axle 180B struts, so you can modify them later to the same big brakes that many modified
1600's use. As the previous guy said, you first need to put the stanza lower arms and radius rods in to enable the strut to go onto the balljoint. Also you will need to carve off the
spring cup and weld on a 1200 one, and then use the 1200 spring and strut top. This was discussed in a previous thread.
