Just looked at the video. Nice job.
Couple of things. If you have a broken or siezed shift cable, the easiest way is to drop the gearhousing straight off the drive shaft housing. That removes the lower shift shaft from the upper shift shaft and means you can then remove the drive shaft housing from the bell-housing without the need to have the shift cable in forward.
Next. That tube infront of the shift shaft coupling point is the speedo pitot tube, and it's a 'click' fitting. There is a section you left on the gear housing that just pops off when you squeeze the fitting. It stays on the end of the tube you pulled off.
When removing the trim switches (on the sides of the gimbal ring), don't remove the 4 cover screws from the assembly, just the 2 mounting screws.
Look forward to seeing the other parts.
