[HWYSTR455]

The largest port size on the MC almost always goes to the rear, regardless of what size fitting or line you plug into it. That's how I've always been able to tell, but maybe that's not always the case?

Also, I have been told that the largest reservoir always feeds the front brakes.

Many 'universal' masters are the same front/rear, so those you can plumb either way.

Should be able to search the original service manual for an Astro/Safari, and find out for sure. But if it had drum rear, then most likely it would use whichever the smaller reservoir is.
