I'm not sure if this will help or not. I don't have a pic and I've never torn into mine....yet!
But here is the step by step from the Helm manual...
Shift Tube Removel and installation
1) Working from under instrument panel, disconnect the horn and directional signal wires at the connectors.
2) Remove the steering wheel, bushing and the spring from the steering column.
3) Carefully remove the pin that secures the selector lever to the hub and remove the lever.
4) Applicable to auto trans only.....
5) Loosen the two ****** attaching nuts enough to apply pressure on them (toward center) to release the bolt heads from the steering column tube.
6) Carefully work the ****** and slector hub and wires over the upper end of the steering shaft.
7) Slip the shift tube out of the steering column.
8) Starts into the installation of new shift tube....
If this doesn't help, let me know and do some more research. I just got the bronco and I'm still sorting through all the "stuff" that came with it as well as getting familiar with the vehicle itself. BTW I have a 69 with a 302 3 on the tree as well.
Good luck
