Nope, steel sleeves. Why bother with a bronze bushing? Remember on regular 833's the countershaft is a press fit directly into the iron case.
Here's an article that was originally in Mopar Muscle. It describes the "problem" with the 833OD countershaft (the aluminum case and a .005" tolerance vs a light press fit on the regular 833's), as well as the fix, which is a set of steel sleeves pressed into the case.
