Dude, the 5th gear fix is so easy. Courtesy Nissan sends a bunch of stuff you don't really need. Basically, you just need a new synchro, baulk ring, 5th gear, and shift fork. 5th is the very last gear on the stack, so its right on the end when you pop the case off. If you had the trans on a table, you could probably have it done in an hour.
