WB stud pattern

[stickthis]

HZ and WB brakes are the same. All use the girlock alloy caliper. HZ ones being imperial. WB being metric.

WB and HQ to HZ all used 7/16 UNF threads for the wheel studs/nuts.

HX (some) & HZ Girlock callipers look very similar to WB, But WB have a banjo bolt for the brake hose fitting, where HX - HZ brake hose has a threaded end that screws into calliper.

agreed, they are significantly different

You will find that WB had quite a lot of stuff different from the Hz
As the Vb commodore came out in 79 which ran the metric banjo bolts that you talk of and was shared with the WB.
Even thing such as wiring connectors were shared.
The WB statesman was even worse for a mixture of both.
