833 Assembly Woes...

My Brewers Rebuild Kit came with Rollers that
Were All .001 too big! Couldn't get the last one in...
Had to re-use my old rollers to load the Input shaft
All the Needle Bearings for the Cluster fit fine.
But the New Ones for the Input?
I have two sets now, no go.
I did my four speed with a brewer's kit and I found it quite easy..
I'm wondering already if the needle bearings were just fine and you're trying to squish the last one in from inside instead of slipping it behind the other bearings?... I know in a lot of cases you can't just snap the last one in from inside you need to slip it in from the top behind the other bearings... Also I think you have to put the slider like in second gear or first gear or something so they hop over top of the counter shaft...
I know brewers provided a piece of PCV for the counter shaft...
