833 o/d tail shaft housing swap

I hate to say this, but I'm 95% sure you gotta drop the cluster gear on the O/D trans to get the tailshaft/gear assembly out, because of the nature of the gear positioning on the cluster.

The non-O/D trans, the tailshaft/gears can be finessed out without dropping the cluster.

Be aware the O/D 3/4 slider can be moved too far, and allow the "keys/struts" to move out of position and jamb, or drop out.

Here's a link to a rebuild thread with pics, to help you out, it's not an O/D but it's similar in all respects.
