Nissan Skyline model R31 was built in Japan 8508-9005. It was fitted with a Four Cylinder CA engine, or six-cylinder RB engines, or a Diesel. Australia-built R31 1986-1990 was sold as Skyline (six-cylinder) or Pintara (four-cylinder). Some parts can be used, or modified for use, on a Datsun 1200.

4-bolt 114.3 PCD. Standard wheel on both R30 and R31 is 14". Shouldn't be any problem running 14" wheels over these brakes.

Strut
R31 uses a standard Nissan 2.0" strut, so will bolt to the usual SAP. However you NEED to buy/fabricate a spacer with shear ring as the locating nub is a different size.
