A-833 OD transmission what type is mine? 421,422??

Any after market rods put in the vise and bust the threads off and have them tig welded back on. Or you'll be breaking them one day. They are not threaded rods the threads are friction welded on most of them. The correct rods look like this . Heavy duty. First pic is 4spd , second pic is OD
