The output bearing is the bitch to line up.

The input shaft bearing is one piece, it has a bearing, seal and the shaft part. It is a bitch to get out and a bitch to get in.

I used a big socket and a sledgehammer to get it out. And a 12" length of broom handle and a normal hammer and lightly tapped it in for about 2 hours. It isn’t a very strong bearing if you hit it too hard it will damage the part. Easiest way to do it would be to take the bell housing and the input shaft bearing to a tranny shop and make them do it.
