transmission won't go all the way in

[fishbone1]

Put a new clutch kit, flywheel, slave cylinder, on an 87 ranger. It is an fm145 transmission. trans needs to go in about another 1/2 inch. Input shaft is coupled to splines. I think it is binding at the pilot bearing. Should I pull it all apart and check the inner diameter of the pilot bearing? or just try to pull it together? I know I need to pull it apart again. I am just venting.
