the auto Pb is a PIA to pull i just did my swap and took me 5 days with the puller and it actually broke my puller so i had to take my car to get it dremeled out. If you have some PB blaster or something of that sorts it would make things easier. But it is absolutely necessary to pull
Also if you got a new clutch kit from your local auto parts store it should've came with a new pilot bushing and throwout bearing.
Its also recommended to swap the throwout bearing. If not you'll end up like me having a terrible rattle and having to repull the transmission out to change it. NEW is always better then USED
