sorry I havent put anymore effort into the tranny rebuild options. I can tell you that it doesnt look like the pathfinder syncros are gonna be any good. they appear beefier (the cut of the tooth is different), but they will engage slower.
All in all, it may be best to rebuild with 97+ syncros. 97+ syncros should be whats readily available at Nissan dealers. I know Courtesy Nissan gets them.
