Default Need help...T56 rebuild

I am rebuilding a unit out of a C5 Corvette and what I'm having trouble with is changing the 4th gear blocker and carbon ring. My problem is removing the blocker ring from the shaft. The tapered bearing on the stubby end of the main shaft looks like it will be destroyed if I press the gear and synchro assembly off of the end because it won't make contact with the race, just the outer portion of the bearing.

I've checked a few different threads but can't find what I am looking for. One thread here has it but the pictures wont come up.. shows a little pic of a frog. Anyways, is there a way the the synchro and blocker ring can come off without destroying the bearing on the end of the shaft or should I just press it all off and replace the bearing.

This is the thread I was using for reference:

Specifically:

Flip the mainshaft upside down on the stubby end, (right side of pic below)
-leave the bearing on unless you're replacing it.

(Starting left- large tapered bearing, 1st gear, 1/2 synchro, 2nd gear, 3rd gear, 3/4th synchro. Divider pointed out)

Remove:
Snap ring
3/4 synchro
-Pull 3/4 synchro sleeve off, either tap it off or use a puller
-Pull the synchro hub with a gear puller
Blocker ring
3rd Gear and caged needle bearing, (keep up with the bearings and where they go)
Spacer
Now we're done with the stubby end, flip the mainshafter over.

All help is appreciated.

It will destroy the bearing in most cases.
