Get drive flanges. Cheap, strong, simple.
Contrary to popular belief (who knows how it started) drive flanges are perfectly acceptable on the street. Many OEM trucks have full time hubs.
Now, I've never noticed driveability issues on the street with the hubs locked, which is the same result you'd have from flanges. That said, my turning radius was increased a bit and I think I got a bit more tire scrub on turns. And I don't drive on snow or the like (hey, it's coastal California, ya know?

)
IIRC, the OEM drive flanges were on the NP203 trucks, i.e. those with a center differential, and not on NP205 or 208's, i.e. part-time trucks. Odd, actually, as the front shaft would be open on a part-time truck, so I don't know why it would matter.
In any event, if you can get flanges for a Dana 44 they'd fit the 10b, as the outers are the same for both. As I understand it, the advantage to flanges is that they're stronger than the manual hubs, as they're thicker since they don't have the center locking mechanism. Less moving parts, too.
In the end, though, on a 10b I don't think you're gonna be breaking hubs, -- at least there are lots of other pieces to break first! -- and they're cheap, off-the-shelf, and more flexible than a flange and a heck of a lot more reliable than then automatic hubs.
