I'd love to see what the transverse linkage for an opposite-side mounted master cylinder looks like. However, check these out...
Here's a blown slant with the MC clearly in front of the brake pedal (from Aussie Speedshop):

And here's the "Hemi 245," a different kind of slant used in the Aussie cars. According to Wikipedia, it was introduced in 1970. You can see it is much more upright, like the Ford and GM 6, among other differences.

By the way, since starting this thread this morning, I happened to talk to an older Australian neighbor and he clearly remembers when the slant hit the Aussie market in the 1960s - he says all the gearheads loved them because (unless you were rich and could afford a V8) they were an affordable powerplant that absolutely smoked the other straight sixes on the market: Holden (GM in Australia) and Ford. Unfortunately he didn't have any other information about the particulars of the slant in the righthand drive cars!
