Pilot bushing for 4 speed swap

Update: got the motor cleaned off and decided I should mock the trans up now before I start doing some head work and getting a cam. I put the bellhousing on and put the trans and it fit with ease. So sounds like I don't need to cut the input shaft or drill the crank deeper? I still haven't gotten the bushing, would that affect it? In regards to if I will need to modify the crank or input shaft? Thanks!
