G'day Mate,

I fixed it for ya

I think Cal is asking about fitting a manual trans crank pilot bushing on a 69 slant 6 that uses 5 core plugs in the block. Concerned about crankshafts rear bore diameter for a pilot bushing since engine was originally attached to an auto trans. And wants attaching it to a 62 3 speed manual

Now I get it. They used to make two different outside Dia. bushings available at NAPA. One was for going from a auto motor to a stick that the crank was not machined to fit the standard size bushing. You can make the standard fit cutting it down and adding a taper but you will need to ream the bushing after you install it because if to tight going in. it will make the inside a lot smaller

They also made a bearing and bushing that fit a crank that wasn't drilled at all. But to use this you needed to cut the input shaft shorter on the trans
