833 OD sticking in 4th, chipped synchro

BTW
there are TWO Mopar short-tail A833od boxes.
The slanty has the smaller M/S that uses a 307 bearing and a 904-sized driveshaft yoke.
The everything else box, has the bigger M/S that uses the 727-sized driveshaft yoke, but I just cannot remember about the bearing; it's been over 20 years since I messed with those.
