I used a bronze? bushing from the help section for my application. I messed the first one up pretty bad putting it in,because i was not aware that even though the cranks are drilled,they are not finished ready to accept a bushing. So i used a sand roll on a dremel and grinded the inside of the hole to fit the new bushing. I then hammered the new bushing in (was still a bit tight and i did mess it up a little bit) But i then took the sand roll again and cleaned up the inside of the bushing so that my clutch alignment tool fit in easily but not sloppy.

The trans went in very easily also.
