Hi Guys.

doing a rx7 brake upgrade, called my friendly nissan dealership to order a new brake master cyl.

i have been told there are a heap of them to chose from depending on engine model (turbo or non-turbo), and 2 differnt fitting sizes available for a rb20de r32 skyline (non turbo)

anyone know whether its the 15/16 size fitting or the 1 inch fitting?

or does anyone just know a model number, or a VIN number for a skyline that i can use?

help is appreciated.
