1972 Front Disc Brake Conversion

just to note, and it probably won't be useful


with a set of disk brake spindles that match you upper balljoint
you can have any combination of
big or small bolt pattern hubs or big or small top balljoint
with a caliper pads and rotor that fits a 14 inch wheel

its just hard work and you would need to import the parts

as far as i can tell the US had a s swap over to 4.5 inch PCD with big upper balljoint
the australians and south africans did not, the change to 4.5 PCD was in isolation for 1971 and they stuck with the small upper joint

means you can add to the mix of US parts

small balljoint non vented rotor 4 inch PCD 14inch wheels 2 pot caliper Australian Valiant VC and VE models
small balljoint none vented rotor KH pin sliders 4 inch PCD 1 pot slider VF and early VG models
small balljoint vented rotor KH pin sliders 4.5 inch PCD 1 pot slider VG
Small balljoint vented rotor Girling Lockheed Girlock claw slider, the short bracket, 1 pot slider VH VJ VK models from 1971 until 1976

all working on the type of spindle that takes the small upper joint with the small inner hub bearing

and all working with 14 inch wheels

all spindles take a caliper with a 3.5 inch centres mounting so you can mix and match
so you can fit either US hub/rotor and caliper
or Australian Hub/Rotor and caliper and the small inner bearing hub came in 4 and 4.5 inch PCD

you can not fit a US caliper to an australian bracket, the brackets are matched to the calipers
but a set of the other countries complete calipers. not a problem

apologies apart from saying what's possible its a post of useless info... :)
