My co-workers at Suntour and I visited Nishiki warehouses around the country to retrofit those bikes with new freewheels and chains, to improve the shifting.
Cool insight, thanks for the info. Most everything I've read about the a-3000 has been less than complimentary.

You're right, I measured from the outside. Inside measurement is 126mm.

The hubs are newer; Quando brand. I could not find a serial or part number. Not sure how to measure the hub axle width, since both hubs have a quick-release on one side. Measure from the base of the quick-release to the end of the post? Rear hub has a 6sp freewheel attached to it. I believe the freewheel is the original SunTour.
Based on all of that, it sounds like a 7sp freewheel/cassette might be the best idea? Is the threading on these generic hubs pretty universal, or will I need to replace the hubs to fit a shimano freewheel? If the treads are the same a move to a rx100 with a shimano hyperglide 7sp freewheel might be the best course of action, as I could keep my current hubs.
But then I'm pretty new at this stuff.
