hi i have b18c gsr obd 2 lsd transmission 3rd gear has synchro issues started a few years ago which id like to replace this winter.

my question is should i just replace the 3rd gear spring and lined synchro or go for the rebuild kit which Includeds: 1-5 Pro-Series Carbon Lined Synchros, 1-5 synchro springs, 5 shaft bearings, bearing clip, 2 axle seals, input seal, shift rod seal, and a new dust boot.

let me know your opinions thanks
