The D44s started in '93 when they started using the Isuzu engine, at least on the 4X4 Rodeos. I believe that the 4X2 Rodeos kept using the 10-bolt for several years. Those are the only Rodeos with drums in the rear.
Some poor guy back east was trying to get the axles out of a '92 Rodeo while working in 6" of snow. He was trying to use the directions for the Isuzu 12-bolt axles, which are not c-clip. None of the usual Rodeo gurus were on the board, so I posted the question here.
I did find that there are a couple of companies that make c-clip eliminator axles, but that seemed like spreading some pretty expensive icing on a cow pie.
