If I can reach it with the first joint of my little finger, it's good.Would I just top it up to right at the fill bolt threads on the housing? I see listed capacity but if I'm wanting to just maintain something close to full, without their being a capacity window/stick/etc., what say ye?
That's how we were taught, that's how each shop I worked at did it, up to the bottom of the fill hole was full, if you could touch it, it was ok.
Since you want it "topped off" then up to the bottom of the hole would be full.
You won't be in trouble if you can touch it with your little finger in the fill hole. The lube is tossed around by the ring gear so it has to be fairly low to be "too low". There's a reason the inside of the casting has the shape and passages that it does - it's to guide the fluid being "slung" by the ring gear to pinion bearings and so on. It's really being "slung about" at highway speeds.
People have asked why are the insides of the housings shaped or cast as they are, why are some covers shaped like they are - it's to guide the fluid being slung by the ring gear.
