Apart from the obvious 15" wheels, does anyone know what you
need in order to fit the SA Big Brake kit to a 1980 Westy?

The 2WD SA kits include:
2 vented rotors
2 replacement hubs
l&r complete calipers
2 brake hoses
4 3.5mm spacer washers (3.5 mm thick) to position calipers
2 metal brake pipe extensions (to locate hoses behind the
strut).

For 1986 to 1991 2WDs you only have to replace your wheel's
hub plus wheel lugnuts (to fit over the studs in the new
hub). Is there more to a pre-86 instalation? Has anyone done
this on an 80?

Thanks,
Chris
