Looks like you're all set then. Get the seal and a new drift pin (for the striking rod you'll have to disassemble) and you should be good to go. These are pieces included in the 5th gear pop-out repair kits by the way. So the 5th gear pop-out thread has pictures and part numbers.
Edit: Apparently Greg's image isn't working anymore, but the Courtesy Nissan ones are.
The seal is labeled 30401-G in this image (keep in mind that is not a real Nissan part number).
The striking rod drift pin is labeled 32873 in this image (keep in m ind that is not a real Nissan part number).
And off to the right you can see there is a drift pin holding the shift selector provision onto the striking rod so that replacement while the transmission in the car should be possible ad I described.
