As indicated in the thread, replace all shifting components or the results could be less than satisfying. engagement teeth are easy to diagnose as worn but what is easily overlooked is the inside diameter of the sliders. They can look like they're in reasonably good condition but if you measure the inside diameter of one with high usage, you'll discover the bore size has increased from the original OEM specs. This can allow the engagement teeth to make contact with the gear teeth prior to complete syncronization resulting in a disconcerting crunch from your freshly renewed gearbox. There's nothing worse than spending the time and money to do it right - twice. If you're that deep, commit to all shifting components (engagement teeth, sliders, balk rings) to avoid disappointment.
