i have a 90 3/4 4wd and i need a new tranny i was reading up on it and wanted to see if anyone knew if you could swap out a tailshaft for a adaptor to a shock t-case?

not really sure what you are asking so maybe you can clarify. But ill take a stab at it. If you want to swap the output shaft you have to tear the whole thing apart anyway so might as well rebuild it at the same time. Other then that i have no idea what you are asking.:confused:
