For whatever reason you decided to go into the transmission, there's a
few things you need to check.
There should be a spec that indicates the clearance of the
sinchronizers. This would indicate a worn synchro ring. Also look
for rounded edges on the synchro teeth.
Look for worn or galled input and output shaft bearings that can
cause noise. rumbling at idle
You will need a dummy shaft and some wire or rope to reinstall the
cluster gear with all it's needle bearings and thrust washers.
I rebuilt a 3 rail for my race car about a year ago. The most difficult
job is getting the cluster back in position without loosing
the needle bearings.
I replaced needle bearings, thrust washers and seals and synchro's
Good luck
